在给定pH值(pH=7.0)和温度(T=25℃)的条件下,采用纳氏试剂比色法(GB7479-87)测定了NH4Cl溶液中蛭石和人造沸石的氨氮平衡吸附量.在平衡吸附量Qe与溶液离子浓度C和介质有效吸附势P关系基础上建立了平衡吸附量Qe与溶质起始浓度C0、吸附介质用量W0的一元二次方程.测试结果证明.这一方程可在较大的C0和W0变化范围内用以描述蛭石和人造沸石的氨氮等温平衡吸附过程.

Tests were conducted to measure the quantity of NH4^＋-N sorption at equilibrium by vermiculite and synthetic zeolite minerals in NH4Cl solution under given pH （pH=7.0） and temperature （T=250C） eondilions. Based on the relation of sorption Q. with solution NH4^＋-N concentration C and the effective sorption potential P at equilibrium, a quadratic equation was established for describing the functional relation of Qr with initial NH4^＋-N concentration Co and sorbent mass quantity W0. Results from the tests indicated relatively high level of ...
