制备了2-巯基苯并噻唑，并对其进行了表征，并将其用于吸附和预富集水溶液中的汞、铅、锌、镉、铜和锰。使用的载体是用硫酸溶液处理过的天然粘土。研究了298K下水溶液中金属离子的吸附等温线与pH的关系，并用间歇法和柱法建立了各金属的定量保留和洗脱条件。化学处理后的粘土对溶液中的HG(II)有很强的选择性，溶液中还含有锌(II)、镉(II)、铅(II)、铜(IT)和锰(II)。
2-Mercaptobenzothiazole loaded on previously treated clay was prepared, characterized and used for sorption and preconcentration of Hg(II), Pb(II), Zn(II), Cd(II), Cu(II) and Mn(II) from an aqueous solution. The support used was a natural clay previously treated with sulphuric acid solution. Adsorption isotherms of metal ions from aqueous solutions as function of pH were studied at 298 K. Conditions for quantitative retention and elution were established for each metal by batch and column methods. The chemically treated clay was very selective to HG(II) in solution in which Zn(II), Cd(II), Pb(II), Cu(IT) and Mn(II) were also present.
