中文摘要:
      本文以天然高分子海藻酸钠和壳聚糖为原料,采用成球分步法制备SA/CTS复合凝胶微球。运用Design—Expert8.05b响应面软件,采用Box-Behnken中心组合原理设计实验来探究合适的微球的制备工艺条件。通过拟合模型优化,复合凝胶微球制备的最佳工艺条件为:SA浓度2.68%、CTS浓度0.94%、氯化钙浓度1.43%。在此预测工艺条件下, SA/CTS复合凝胶微球对铅离子的吸附量为31.48 mg/g,水中溶胀度为93.7%。对合成工艺参数进行结果验证,得到实际吸附量是30.09mg/g,实际水中溶胀度是97.5%,与预测值基本一致,证明研究结果可以作为SA/CTS复合凝胶微球的制备提供参考依据。最后对制备的微球进行红外表征和SEM表征
英文摘要:
      Based on the SA and CTS We have been synthesized Alginate-Chitosan Complex Adsorbent. The processing condition was optimized with response surface method by setting the comprehensive assessment score of adsorption capacity and swelling capacity as optimization target. By using the fitting model to optimize the processing condition, the optimum conditions were determined as follows: SA is 2.68%, CTS is 0.94%, CaCl2 is 1.43%. In this condition, the adsorption is 31.4826, the swelling capacity is 93.74%. The confirmatory experiment showed the adsorption is 30.09mg/g, the swelling capacity is 97.5% and the results could provide references for Alginate-Chitosan Complex Adsorbent. The Adsorbent were characterized by FTIR and SEM
