Notes:
In recent years, chitosan/inorganic composites have attracted increasing attention due toits fascinating properties and potential applications in biodegradable materials, drug release,electrochemical sensor, packaging materials and so on. Chitosan/inorganic composites are expectedto be as an effective way to overcome shortcomings of slow flocculating speed of chitosan particles,not good enough to meet those wide range of applications in wasterwater treatment. In this study,novel chitosan/clay/PAC (polyaluminium chloride) composite was prepared, and it was used intreating effluent from dying and finishing process. One set of orthogonal experiments wereconducted to optimize the experimental condition, and the results showed that removal of waste dyeis affected by the dosage of chitosan, PAC, clay, pH and treatment time. The experiments resultsindicated that the effluent from dying and finishing process treated by the prepared compositesbecame obviously fade, and its COD (chemical oxygen demand) decreased from original1398.2mg/L to 197.6mg/L, the removing rate reached 85.9%
