摘要:
以壳聚糖为原料,用反相悬浮聚合法合成磁性壳聚糖微球(MCS),经进一步改性,制备出磁性灭藻剂——载铜磁性壳聚糖微球.采用傅里叶变换红光谱对样品进行表征,并研究MCS的载铜能力和载铜MCS的释铜性能.研究结果表明:硫酸铜初始质量浓度为750 mg·L-1,MCS用量为15 mg,pH值为5,吸附平衡时间为15 min,温度为25 ℃,是MCS对Cu2+的最佳载铜条件.载铜MCS的释铜量随着时间和用量的增加而增加,且载铜MCS的用量在比较低的情况下,理论上能保证有效
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-1, the dosage of MCS was 15 mg, pH was 5, adsorption equilibrium time was 15 min, temperature was 25 ℃. 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.
