The optimum technological conditions as follows:pH=5, mass ratio of liquid to solid 15 in adsorption and 70% ethanol as eluting agent. Resin could be regenerated after every three time uses. The content of flavonoids glycosides in extracts was about 24%.展开更多
This article reported the preparation of macro porous resin by heating polyproplyene and improving its property.The result showed that macro porous resin with good quality and big soil adsorption rate can be prepared ...This article reported the preparation of macro porous resin by heating polyproplyene and improving its property.The result showed that macro porous resin with good quality and big soil adsorption rate can be prepared when the ration of polyproplyene to soybean salad oil is 1∶2,the highest heating temperature is 250℃,time of homothermal agitation is 20min and the rate of cooling is 2℃/min.The resin can effectively adsorb waste grease in restaurant wastewater.After removing grease,wastewater is treated with cogulant deposition.COD cr descend to 83mg/l from 790mg/l,which can reach the national discharge standards.展开更多
