Polythiourea resin was synthesised with thiourea and formaldehyde and characterized by Fourier transform infrared spectroscopy (FT-IR). The effects of temperature, time, pH and initial concentration on the properties of polythiourea resin adsorption influence to silver ions were discussed by static adsorption method. In addition, experiments have also been carried out on the study of adsorption isotherm. In order to further understand the adsorption characteristics of polythiourea resin, the adsorption functional characteristics of Ag(Ⅰ) were studied by density functional B3LYP method. 相似文献
