| Abstract: | The pretreating peanut shell granular(20-60 mesh)is grafted with epichlorohydrin, and added with active chlorine;while the active chlorine is substituted by thourea.the chelate resin with thiourea group is obtained. The optimun conditions of technique are: (1)Synthesising etherial granular, the reacting time is 4 h,the reacting temperature is 90 ℃; (2)Substituting and adding thiourea group. the reacting temperature and time are 90 ℃ and 2 h respectively. The adsorbability of chelate resin for Ag(l) is 100 mg/g while the pH value of solution equals to 5. 4-5. 8. |
