摘要
研究了混合酸法交联改性多孔淀粉的处理条件,研究表明:混合酸加入量为淀粉干重的5%,柠檬酸∶乙酸酐(g/mL)为1∶30,温度40℃,时间120min为最佳改性工艺条件。混合酸交联改性处理后的多孔淀粉保持了多孔淀粉的孔结构,使吸附物的承载能力得到加强。
The mix acid cross-linked porous starch process condition was studied.The research indicated that:the mix acid joined the quantity for the starch dry weight 5%, citric acid to the second grade acid anhydride(g/mL) was 1:30,the temperature was 40℃,time 120min was the best modified technological conditions.After the mixed acid cross-linked processing porous starch maintained the porous starch hole structure,strengthened the ability to absorption.
