摘　　要：研究了聚丙烯基强酸离子交换纤维对蔗糖清汁中钙离子的脱除工艺。结果表明,纤维对蔗糖溶液中的Ca2+脱除率高,脱除量大,达到54.9mg/g。当纤维与蔗糖溶液的质量体积比例为1g/135ml时,纤维对Ca2+的脱除率达到95%以上。随着温度的升高和Ca2+含量的增大,纤维对Ca2+的脱除率逐渐降低。吸附饱和后的纤维可用1.0mol/L的HCl溶液再生,再生纤维重复多次使用后对Ca2+的脱除容量保持不变。Technology of cation exchange fiber was studied to remove of calcium during cane sugar production. The fiber has excellent absorption ability for Ca2+ which is about 54.9 mg/g. The highest extraction rate for Ca2+ can reach 95% when the proportion of the fiber to sugar liquor is 1 g to 135 ml. But the extraction rate for Ca2+ reduces with the increase of temperature or the concentration of Ca2+. The fiber can also be regenerated by eluting with 1.0 mol/L HCl and its capacity changes little after reused for ...
