  • The morphology and structural characteristics of composite flocculant PSAF-CTS were examined using infrared spectroscopy and scanning electron microscopy. The infrared spectroscopic results indicated that a hydrogen bonded polymer of PSAF and CTS was first created through hydrogen bonding, followed by a dehydration step under acidic conditions. The end products of multi-polymer coordination compounds PSAF-CTS were formed through the coordinations of hydroxy-type bridges. Three major types of structures in the composite flocculants were identified as PSAF、CTS and a porous honeycomblike combination as observed by scanning electron microscopy. In addition, the morphology and structures of the formed PSAF and CTS after reactions were altered compared to those prior to reactions. Great removal efficiencies using such flocculants were obtained in the treatments of four types of wastewaters.

Abstract: The morphology and structural characteristics of composite flocculant PSAF-CTS were examined using infrared spectroscopy and scanning electron microscopy. The infrared spectroscopic results indicated that a hydrogen bonded polymer of PSAF and CTS was first created through hydrogen bonding, followed by a dehydration step under acidic conditions. The end products of multi-polymer coordination compounds PSAF-CTS were formed through the coordinations of hydroxy-type bridges. Three major types of structures in the composite flocculants were identified as PSAF、CTS and a porous honeycomblike combination as observed by scanning electron microscopy. In addition, the morphology and structures of the formed PSAF and CTS after reactions were altered compared to those prior to reactions. Great removal efficiencies using such flocculants were obtained in the treatments of four types of wastewaters.
