摘要：
Degradation of carbamazepine (CBZ) was first conducted by electrochemical activation of persulfate (PS) in flow-through system using boron and cobalt co-doped TiO2 nanotubes (B, Co-TNT) as the anode and carbon felt (CF) as the cathode, achieving a higher removal efficiency than that in beaker mode ascribed to the higher PS decomposition for center dot OH production. Different operating parameters including applied current, initial pH, PS concentration and flow rate were explored, supporting that high current, acidic condition, lofty PS concentration and flow rate were beneficial for the removal of CBZ. The mechanisms of CBZ degradation by electrochemical activation of persulfate in flow-through system were the comprehensive effect of center dot OH, SO4 center dot- and O-1(2), and the possible CBZ degradation pathway was proposed. In summary, B, Co-TNT anode coupled with CF cathode in flow-through system by electrochemical activation of persulfate was an effective method for contaminants degradation.

摘要：
In this work, experimental and theoretical methods were used to investigate the role of poly aluminum chloride on thallium removal in the liquid phase. Experimental results indicated that poly aluminum chloride mainly played the role of absorbent. Meanwhile, it exhibited a certain catalytic effect in the chemical precipitation process. Theoretical results indicated that the bridge site between two Cl atoms was easier to adsorb Tl+ and Tl3+. Al2(OH)4Cl2 and [Al2(OH)4Cl2]2 were conducive to the adsorption of Tl+ and Tl3+ respectively. Further-more, excessive Cl atoms were not conducive to the adsorption of Tl+. The third Tl-OH generation step was the rate-determination step of generating Tl(OH)3, and the first Tl-S generation step was the rate-determination step of generating Tl2S. Al2(OH)2Cl4 and [Al2(OH)4Cl2]2 decreased the maximum reaction barrier of generating Tl-S and Tl-OH, which enhanced the removal of Tl.

摘要：
The development of novel catalysts for degrading organic contaminants in water is a current hot topic in photocatalysis research for environmental protection. In this study, C(3)N(5) nanosheet/Ag(2)CO(3) nanocomposites (CNAC-X) were used as efficient photocatalysts for the visible-light-driven degradation of methylene blue (MB), and tetracycline hydrochloride (TC-HCl) was synthesized for the first time using a simple thermal oxidative exfoliation and in situ deposition method. Due to the synergistic effect of nanosheet structures, carbon defects, and Z-scheme heterojunctions, CNAC-10 exhibited the highest photocatalytic activity, with photodegradation efficiencies of 96.5% and 97.6% for MB (60 mg/L) and TC-HCl (50 mg/L) within 90 and 100 min, respectively. The radical trapping experiments showed that ·O(2)(-) and h(+) played major roles in the photocatalytic effect of the CNAC-10 system. Furthermore, intermediates in the photodegradation of MB and TC-HCl were investigated to determine possible mineralization pathways. The results indicated that C(3)N(5) nanosheet/Ag(2)CO(3) photocatalysts prepared in this work could provide an effective reference for the treatment of organic wastewater.

摘要：
A Liquidambar formosana plantation is a kind of fast-grown forest in the subtropical region, providing a variety of ecosystem services such as superior wood, carbon fixation and oxygen release, and biodiversity maintenance. However, the ecological service function value of Liquidambar formosana plantations is not clear. To gain insights into the characteristics and importance of its ecological and economic benefits, the Liquidambar formosana plantation in the Tianjiling Forest Farm of Changsha City was taken as the specific research object in this paper. The ecological service function evaluation index system for Liquidambar formosana plantations was established based on the relevant research worldwide and the actual situation. The market value method, shadow engineering method, carbon tax method, and other environmental economics methods were used to estimate the value of seven ecological service functions (including organic matter production, carbon fixation and oxygen release, water conservation, soil conservation, soil improvement, air purification, and biodiversity maintenance) of the forest of Liquidambar formosana. The results indicated that the total economic value of ecological service function provided by the Liquidambar formosana plantation of Changsha was 103,277.82 RMB/(hm(2)center dot a), and the indirect economic value was 8.47 times that of the direct economic value. Among the seven ecological service functions, the value of carbon fixation and oxygen release was the highest (36,703.33 RMB center dot hm(-2)center dot a(-1)), thus suggesting that the Liquidambar formosana plantation had strong photosynthesis and significant carbon fixation. This study directly reflects the value of forest ecological service function in the form of currency, which is beneficial to provide more insights into forest ecological service function so as to provide basic data and a scientific basis for the protection, construction, and promotion of the sustainable utilization and development of urban forest resources.

摘要：
Although microbial remediation has been widely used in the bioremediation of various contaminants, in practical applications of biological remediation, pure cultures of microorganisms are seriously limited by their adaptability, efficiency, and capacity to handle multiple contaminants. Mixed cultures of microorganisms involve the symbiosis of two or more microorganisms. Such cultures exhibit a collection of the characteristics of each microorganism species or strain, showing enormous potential in the bioremediation of organic or heavy metal pollutants. The present review focuses on the mixed cultures of microorganisms, demonstrating its importance and summarizing the advantages of mixed cultures of microorganisms in bioremediation. Furthermore, the internal and external relations of mixed culture microorganisms were analyzed with respect to their involvement in the removal process to elucidate the underlying mechanisms.

摘要：
The disposal of biomass enriched with heavy metals (HMs) limits the application of phytoextraction. This study investigated the feasibility of obtaining K-rich fertilizer with low risk of HMs and biochar with good application prospect by extracting Napier grass biochar using 15% HNO(3) and separating HMs from the filtrate using 40% KOH. In this study, Napier grass biochar produced at 500°C showed better potential for utilization owing to its relatively low HM contents, high nutrient contents, and high yield. In fact, 61.26% Cd, 84.22% Zn, and more K were extracted from biochar when the pH was adjusted to 1 using 15% HNO(3). Then, Cd and Zn could be almost separated from the filtrate by adjusting the pH to 10 or more by adding 40% KOH. The Cd content in the biochar was reduced from a low risk level to a no-risk level, and the Zn content in the biochar was reduced from a medium risk level to a low risk level when the pH was adjusted to 1 and 2 by adding 15% HNO(3). The adsorption capacity of biochar to dyes was enhanced when the pH was adjusted to 1 using 15% HNO(3). The cation exchange mechanism endows the biochar with better potential for reuse (for methylene blue). This work provides a safe, efficient, and maneuverable resource allocation method.
