新型SG树脂对贵金属吸着行为及吸着机理的初步探讨
Adsorption behaviour of new SG chelating resin for noble metals and its possible adsorption mechanism
【摘要】 研究了新合成的以交联苯乙烯-二乙烯苯为骨架的胍基螯合树脂(SG)吸着金属的行为,以及SG 在 HCl、H2SO4、铵盐(NH4Cl 和 NH4NO3)介质中吸着贵金属的分配系数和吸着率。给出了各种贵金属的吸附速率的曲线、吸附等温线及温度影响的曲线。提出了树脂吸附贵金属的可能机理。
【Abstract】 SG Chelating resin is one which containsguanidine as the functional group.We havestudied its adsorption behaviour against noblemetals.The distribution coefficients and thepercentage of adsorption in several media,suchas H2SO4,HCl,NH4Cl and NH4NO?,were inves-tigated.Characteristics of adsorption,rate,isotherms and thermodynamics were also studied.The possible adsorption mechanism was given.
