摘要

以氯甲基化聚苯乙烯微球为原料

经过两步反应制得巯基聚苯乙烯树脂

用红外光谱测试、比表面分析、元素分析及热重分析表征了该巯基聚苯乙烯树脂

测试了此巯基聚苯乙烯树脂对含Hg2+烟气、脱硫废水及脱硫浆液的脱汞性能。分析测试表明:巯基聚苯乙烯树脂热稳定性好

能有效脱除烟气、脱硫废水及脱硫浆液中的Hg2+。巯基聚苯乙烯树脂对烟气中Hg2+的脱除效率大于90%

对脱硫废水及脱硫浆液的脱汞率接近100%。将此树脂置于脱硫系统内

能捕捉脱硫系统内的Hg2+

避免Hg2+进入脱硫石膏而造成脱硫石膏中汞的再释放。用6mol·L-1盐酸洗脱捕捉了Hg2+的巯基聚苯乙烯树脂

再生3次后

巯基聚苯乙烯树脂的再生率仍高达90.2%。

Abstract

Thiol polystyrene resin was prepared by two-step reaction with chloromethyl polystyrene resin as material

and then it was characterized by Fourier transform infrared spectroscopy

Brunauer-Emmett-teller

elemental and thermogravimetric analyses. The Hg2+ removal performance of thiol polystyrene resin was also investigated in simulated flue gas containing Hg2+

desulfurization effluent and desulfurization slurry. It was found that thiol polystyrene resin possessed high thermal stability and could be used as an absorbent for Hg2+ removal from flue gas

desulfurization effluent and desulfurization slurry. The thiol polystyrene resin showed Hg2+ removal efficiencies above 90%

100% and 100% in flue gas

desulfurization effluent and desulfurization slurry

respectively. The placation of thiol polystyrene resin in the wet flue gas desulfurization system could capture Hg2+ in this system and avoid its entering to desulfurization gypsum

which could bring the mercury reemission. Moreover

thiol polystyrene resin captured Hg2+ was regenerated successfully by 6 mol·L-1 HCl and its regeneration rate with three times regeneration reached up 90.2%.
