摘要
用线型环氧酚醛树脂(F44)与苯基硫脲合成了酚醛型苯基硫脲螯合树脂(F44 PTU),研究了该树脂对Au(Ⅲ)的静态及动态吸附性能.结果表明,该树脂对Au(Ⅲ)具有较快的吸附速率,其表观吸附速率常数为0 0055s-1,树脂的吸附为吸热过程,在有其他金属离子共存时,树脂对Au(Ⅲ)具有较好的吸附选择性.一定条件下,树脂可以洗脱再生.
A kind of epoxyphenolic phenylthiourea resin is synthesized and its adsorption properties for Au(Ⅲ) ion are studied. The results show that F_(44)-PTU resin has good adsorption properties and selectivityfor Au(Ⅲ),its apparent adsorption velocity is 0.0055 s^(-1).The resin can be desorpted and regenerated.
