Abstract A new water purifying agent is a kind of ropy liquid which contains ferric oxide over 5 wt%, alumina over 9 wt% and calcium oxide over 6 wt% and has a pH value of 5.0-7.0 and a density 1.30-1.35. It is prepared through polymerization with hydrochloric acid, iron powder and calcium aluminate as raw materials and the preparation process is a simple process needing to heating. It has obvious purifying effect on water by reducing its color, turbidity, smell and suspension.
