The reaction of 1,3-dipropyn-2-yloxycalix[4]arene with mercury(II)acetate could give mercury-containing alkynyl calixarenepolymer.The extraction behavior of 1,3-dipropyn-2-yl-oxycalix[4]arene towards mercury(II)ion was examined.When the moleratio of Hg~(2+)/calixarene was 1:1,the extractive percent can reach to 99.1%,and the extraction capacity was up to 431 mg/g.It couldalso decrease the Hg~(2+)concentration from 5 to 0.85 mg/L,which was only 17%of the national standard of effluent and satisfied thenational standard of drinking water.The extraction process included chemical reaction.
The reaction of 1,3-dipropyn-2-yloxycalix [4] arene with mercury (II) acetate could give mercury-containing alkynyl calixarene polymer. The extraction behavior of 1,3-dipropyn-2-yl-oxycalix [4] arene towards mercury (II) ion was examined. Having the moleratio of Hg 2+ (2 +) / calixarene was 1: 1, the extractive percent can reach 99.1%, and the extraction capacity was up to 431 mg / Hg 2+ concentration from 5 to 0.85 mg / L, which was only 17% of the national standard of effluent and satisfied thenational standard of drinking water. The extraction process included chemical reaction.
