摘要
制备含有2,4,6-三硫代三聚氰酸钠(TMT)的多孔高分子滤板,测定了该滤板对水溶液中Pb2+的吸附性能。讨论了溶液温度、pH值和流速对吸附性能的影响。结果表明:它对Pb2+具有较高的吸附容量和较快的吸附速度。铅离子的去除率超过90%,高分子滤板经再生实验后可循环使用。
A porous macromolecule filter plate containing 2,4,6-trimercaptotriazine, trisodium salt （TMT） was prepared. The adsorption properties of the filter plate for lead ion were studied in aqueous solution, with analysis of the effect of temperature, pH value and rate on adsorption capacity. Results showed that the porous macromolecule filter plate had high adsorption capacity and rapid rate for pb2＋, with the efficiency of removing lead ion above 90%. The porous macromolecule filter plate can be reused as well.
