Different compositions of the cationic surface active agent,Arquad 2HT-75,with other two clarificants were used in floating purification experiments of the affination raw sugar. The results show that the 2HT-75 and P?2O?5 is the optimum composition.

• 用阳离子表面活性剂Arquad2HT-75分别与两种澄清剂组合对复筛原糖浆进行气浮清净试验,结果显示,2HT-75与P2O5的组合最优。
