Abstract:

Using the waste pickle containing chlorhydric acid as a raw materical, with one step method of catalytic-oxidation-hydrolysis-polymerization, the industrial tests of the preparation of polyferric chloride were introduced.A stabi-lizer which could keep the products from hydrolysis was used.So that a new way for utilization of waste pickle of chlorhydric acid was provided.The good social effect, fine environmental benefit and nice economic profit can hopefully be gained.

Key words: waste pickle containing chlorhydric acid, polyferric chloride, flocculation
