【 摘 要 】
The solid waste of iodized-salt industry are sapon (50-100 kilograms) and blotong (1-2 tons) per 10 tons per day. The objective of this research was for recycling blotong through purification, recrystallization and in situ iodisation to increase NaCl content and homogeneous KIO 3 . This research used two variables which were KIO 3concentration within 30,40, 50 & 60 ppm, and brine water of blotong that had soluted into 24 0 Be (consist of salt water which purified with Na 2 CO 3,NaOH and unpurified salt water). The composition of blotong were 12.318% water content, 46.409% Cl - , 82.685% pure NaCl, 0.784% Mg 2+ , 1.420% Ca 2+and 2.747% SO 4 .After purification and recrystallization, impurities was decreased, Mg 2+became 0.278% (64.54% reduction) and Ca 2+became 0.153% (89.23% reduction). NaCl content was increasing into 96.481% and fulfilled the NaCl standard of salt consumption based on SNI 3556-2010 (94.7%).
