摘　　要：本文以微乳液法合成的ZnS纳米粒子作为吸附剂,研究该吸附剂对溶液中有机染料的吸附性能。结果表明,纳米ZnS对有机染料的吸附受溶液pH值的影响,在溶液pH=4.0的条件下达到最大吸附容量。纳米ZnS对有机染料具有一定的吸附能力和良好的吸附动力学特性,其吸附行为基本符合Langmuir吸附等温式。The adsorbent of ZnS nanoparticles was prepared by microemulsion method and the adsorption performances of theabsorbents to organic dye in aqueous solution were investigated. The results showed that the pH of solution significantly affectedthe adsorption, and the maximum adsorption capacity was achieved at pH=4.0. The ZnS nanoparticles sorbent had a certain abilityof adsorption and good kinetic property for organic dye.The adsorption of organic dye on the adsorbent accorded with Langmuiradsorption behavior.
