Abstract:

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 many times.

Key words: cane sugar, calcium, ion exchange, removal, regeneration
