| 摘 要： | 在四丁基溴化铵(TBAB)相转移催化条件下,线形环氧酚醛树脂(F44)与苯基硫脲(PTU)发生开环加成,合成了负载苯基硫脲的酚醛型螯合树脂(F44-PTU).研究了该树脂对Cu2 、Ni2 、Pb2 、Hg2 、Au3 的吸附容量及温度、离子浓度、pH值对Ag 吸附性能的影响.结果表明,该树脂对Ag 具有较好的吸附性能,吸附符合Freundlich等温式.吸附树脂在5%硫脲～1mol/L HNO3时可洗脱再生,再生后树脂的吸附能力下降,可能在Ag 的吸附过程中伴随有氧化还原作用.将合成树脂处理实验室含银废液,银的回收率可达93.8%. |

| Abstract: | A novel resin of phenylthiourea supported phenolic aldehyde has been synthesized by the reaction between F44 and PTU under the condition of PTC. Adsorption properties of the resin for Cu2+, Ni2+, Pb2+, Hg2+, Au3+ and Ag+ have been studied. The effect of temperature, ionic concentrate and pH on adsorption behavior for Ag+ has been investigated. The results show that the resin has good adsorption properties for Ag+. The adsorption has the character of Freundlich. The adsorbent resin can been regenerated by 5% thiourea~1mol/L HNO3 solution, while adsorption capacity of regenerated resin decrease with oxidation-reduction. The resin can be used in laboratory wastewater of Ag+, 93.8% of Ag+ has been recovered. |
