The intrinsic viscosity and viscometric interaction parameters of perfluorosulfonic acid(PFSA) and poly(vinyl alcohol)(PVA) were measured by dilute solution viscometry.The miscibility between PFSA and PVA was estimated by the criteria of △B and μ.The results indicated that PFSA and PVA were completely miscible for any weight fraction in aqueous solution. 相似文献

利用Na2SiO3和Al2（SO4）3为原料在35℃条件下制备了无机高分子絮凝剂聚硅酸硫酸铝（polymericsilicatealuminumsulfate,PASS）,并利用自制高岭土悬浮液为模拟废水对制备的PASS性能进行了评价。对Al3＋／SiO2摩尔比、聚合时间、搅拌、pH、陈化时间等制备条件进行了系统研究。实验结果表明,制备PASS时Al3＋／SiO2摩尔比nAP3＋／nSiO3为1、聚合时间为10d、搅拌速率在1000rpm、搅拌时间为90min、陈化时间为1h、pH在3-5．5之间时较为合适,PASS对模拟废水浊度脱除率最高达到97％以上。 相似文献
