Abstract
PURPOSE: To manufacture a raw material for flocculant having excellent flocculating characteristics from reaction of a soluble aluminum salt and a soluble iron salt in a fixed ratio in an aqueous medium containing an alkali carbonate.
CONSTITUTION: A precursor for a floculatn of Al-Fe hydroxides containing amorphous carbonic acid radical soluble in hydrochloric acid is obtained from neutralization of a soluble Al salt (e.g., sulfate, nitrate, chloride, etc.) and a soluble Fe salt (e.g., sulfate, nitrate, chloride, etc., of trivalent Fe) in a Fe2O3/R2O3 ratio X of 0.01W 0.88 (where R2O3 is sum of Al2O3 and Fe2O3 in molal concentration) and a CO2/R2O3 ratio of ≥0.1 under a condition that pH value meets the relationship 6.5W0.7 X or 9.8W1.1 X. Then, the precursor thus obtained is dissolved in hydrochloric acid, etc., to manufacture a flocculant having excellent flocculating characteristics, having a basisity Y≤84, represented by the formula (I), and Fe2O3/R2O3 ratio X≥0.01 (in such a way as to meet the relationship Y≥72X+21), a pH of 2.5W3.5, and a total Al2O3+Fe2O3 content of 5W30%.
