中文摘要：

Polyquaternium-6 (PQ6 ) 作为水溶性的聚合物被用于阴离子在 ultrafiltration 前钨(VI ) 形成的 complexing。钨(VI )-PQ6 建筑群被 polysulfone 保留在 complexation-ultrafiltration 过程的空纤维 ultrafiltration 膜。象聚合物金属比率(PMR ) 那样的各种各样的操作参数的效果， pH 和氯化物离子集中在上渗入流动(J) 和钨拒绝系数(R) 被调查。包括改革聚合物的集中， decomplexation， diafiltration 和复用的四个实验的集成被执行。在集中的过程， J 慢慢地衰退， R 在 3 的 PMR 和 7 的 pH 是大约 1。在 retentate 的钨集中与体积集中因素线性地增加。钨与膜高效地被集中。集中的 retentate 为 decomplexation 进一步被使用。在 50 mgL1 的氯化物离子集中到达 decomplexation 平衡拿大约 6 min。钨(VI ) 的 decomplexation 百分比 -PQ6 建筑群活动范围 56.1% 。在 diafiltration 过程，钨(VI ) 能被使用改革 PQ6 的 50 mgL1 氯化物离子答案，和纯化有效地提取是可欣然接受地令人满意的。改革 PQ6 被用来在各种各样的 pH 价值绑钨(VI ) 。改革 PQ6 的有约束力的能力接近新鲜 PQ6 的，并且有约束力的能力的恢复百分比比 90% 高。

英文摘要：

Polyquaternium-6 （PQ6） as the water-soluble polymer was used for complexing the anion forms of tungsten （Ⅵ） before ultrafiltration. Tungsten （Ⅵ）-PQ6 complex was retained by polysulfone hollow fiber ultrafiltration membrane in the complexation-ultrafiltration process. Effects of various operating parameters such as polymer metal ratio（PMR）, pH and chloride ion concentration on permeate flux （J） and tungsten rejection coefficient （R） were investigated. The integration of four experiments including concentration, decomplexation, diafiltration and reuse of regenerated polymer was carried out. In the process of concentration, J declines slowly and R is about 1 at PMR of 3 and pH of 7. Tungsten concentration in the retentate increases linearly with volume concentration factor. Tungsten is concentrated efficiently with the membrane. The concentrated retentate was used further for the decomplexation. It takes about 6 min to reach the decomplexation equilibrium at chloride ion concentration of 50 mg·L-1 . The decomplexation percentage of tungsten （Ⅵ）-PQ6 complex reaches 56.1%. In the diafiltration process, tungsten （Ⅵ） can be extracted effectively by using 50 mg·L-1 chloride ion solution, and the purification of the regenerated PQ6 is acceptably satisfactory. The regenerated PQ6 was used to bind tungsten （Ⅵ） at various pH values. The binding capacity of the regenerated PQ6 is close to that of fresh PQ6, and the recovery percentage of binding capacity is higher than 90%.
