磁性灭藻剂的制备及性能分析
Preparation and Characterization of Magnetic Algicide
摘要
Abstract
With chitosan as raw material, magnetic chitosan microspheres (MCS) were prepared through inverse suspension cross-linking, then a new magnetic algicide—magnetic chitosan microspheres carrying copper (i. e. MCS-Cu) was prepared by further modification, and its structure was characterized by infrared spectrum. The adsorption ability of MCS toward Cu2+ and desorption performance of MCS-Cu toward Cu2+ were studied. Results showed that the optium adsorption as follows: initial concentration of Cu2+ was 750 mg · L ', the dosage of MCS was 15 mg, pH was 5? adsorption e-quilibrium time was 15 min, temperature was 25 °C. The quantity of Cu2+ released from MCS-Cu increased with time extending and raise of MCS-Cu dosage, and theoretically, it could guarantee removal efficiency of algae efficiently and continually. But the quantity of Cu2+ released from MCS-Cu didn't change obviously when pH varied from 6 to 8.关键词
