A Study on the Preparation and Flocculation Properties of Boracic Poly-Aluminum-Ferric-Silicate

Abstract:

The boracic poly-aluminum-ferric-silicate (B-PSAF) coagulant was prepared by water solution co-polymerization method, which was synthesized from sodium silicate, aluminum sulfate, ferric chloride and sodium borate. In addition, the best molar ratio of boron and silicon was determined by single factor process. The micro-morphology and structure of B-PSAF were studied by scanning electronic microscope (SEM) and Fourier transform infrared spectrum (FT-IR). It has been studied the operation of B-PSAF as the flocculating agent, the dosage and its effects on the flocculability. Experiments show that B-PSAF is a good effective flocculant, which can be used to treat alkaline dyeing wastewater and it has the features of less consumption, rapid coagulation and high removal rate of COD_Cr.
