摘要:
通过戊二醛化学改性交联竹浆纤维素和丝胶蛋白,并通过改变反应温度、pH、时间、戊二醛的用量比和丝胶的用量比来控制反应条件,制备出纤维素丝胶全降解绿色絮凝材料(Bamboo pulp cellulose-g-silk sericin,BPC g SS)。采用傅立叶红外吸收光谱(FT IR)、场发射扫描电子显微镜(FE SEM)和Zeta电位分析仪对最优BPC g SS产品进行表征分析,并进一步用BPC g SS对高岭土模拟废水进行了混凝研究。结果表明:在反应温度37 ℃、反应pH值为4-5、反应时间8 h、戊二醛用量0- 4 g、丝胶用量1-2 g条件下得到最优产品;该BPC g SS的混凝效果随废水pH值、絮凝剂和助凝剂用量有较大变化;采用最优产品对高岭土模拟废水和实际工业印染废水进行混凝处理,CaCl 2用量0-4 mg/mL、pH值为4,高岭土废水平均浊度去除率可达98 4%,印染废水平均浊度去除率达到95 3%,印染废水COD去除率达到97 0%。在土壤提取液中90 d 后,BPC g SS的降解率达到92 8%。
