Research on the Use of Ferrite Magnetic Fluid for Purification of Waste Waters from Printing and Dyeing

摘要

The optimum types and quantities of aggregating agents, as well as pH values, temperature, oxygen concentration, etc., were experimentally determined for purification of processing waters for recycling. Ferrite, when surrounded by a layer of polar molecules of aliphatic acid plus a layer of nonpolar paraffin molecules, was found to have extensive applications for recovery and treatment of twice its own quantity of waste residues.
