•  最佳pH值：尽管其适用范围较广，但研究表明，聚合氯化铝在pH值为6.5到7.6时表现出最佳的絮凝效果。[⁠⁣ ⁠⁣](https://mip.b2b168.com/wvs71677194.html)[2](https://mip.b2b168.com/wvs71677194.html)[⁠⁣ ⁠⁣](https://baike.baidu.com/item/%E8%81%9A%E5%90%88%E6%B0%AF%E5%8C%96%E9%93%9D%E6%B6%B2%E4%BD%93/16551838)[7](https://baike.baidu.com/item/%E8%81%9A%E5%90%88%E6%B0%AF%E5%8C%96%E9%93%9D%E6%B6%B2%E4%BD%93/16551838)[⁠⁣ ⁠⁣](https://baijiahao.baidu.com/s?id=1826057550767710352)[9](https://baijiahao.baidu.com/s?id=1826057550767710352)[⁠⁣ ⁠⁣](https://baijiahao.baidu.com/s?id=1824509516138456339)[10](https://baijiahao.baidu.com/s?id=1824509516138456339)[⁠⁣ ⁠⁣](https://www.baike.com/wikiid/4538558786618115451#offline_html_corpas)[11](https://www.baike.com/wikiid/4538558786618115451#offline_html_corpas)[⁠⁣ ⁠⁣](https://m.baike.com/wikiid/4538558786618115451)[12](https://m.baike.com/wikiid/4538558786618115451)[⁠⁣ ⁠⁣](https://www.baike.com/wikiid/4538558786618115451?from=wiki_content&prd=innerlink&view_id=tpixv677g9s00)[13](https://www.baike.com/wikiid/4538558786618115451?from=wiki_content&prd=innerlink&view_id=tpixv677g9s00)[⁠⁣ ⁠⁣](https://m.bestb2b.com/business_184636320.htm)[15](https://m.bestb2b.com/business_184636320.htm)[⁠⁣ ⁠⁣](https://bookshelf.docin.com/touch_new/preview_new.do?id=777358761)[16](https://bookshelf.docin.com/touch_new/preview_new.do?id=777358761)

•  不同pH条件下的表现：

•  酸性条件（pH < 5）：在较低的pH值下，聚合氯化铝会释放出更多的氢氧化铝离子（Al(OH)₄⁻），这理论上可以增强絮凝效果。然而，过低的pH值会导致混凝效果不佳。[⁠⁣ ⁠⁣](https://k.sina.cn/article_7733659346_1ccf646d200101c0u8.html?cre=wappage&from=science&loc=2&mod=r&r=0&rfunc=85&tj=cx_wap_news_relate)[5](https://k.sina.cn/article_7733659346_1ccf646d200101c0u8.html?cre=wappage&from=science&loc=2&mod=r&r=0&rfunc=85&tj=cx_wap_news_relate)[⁠⁣ ⁠⁣](https://mparticle.uc.cn/article.html?uc_param_str=frdnsnpfvecpntnwprdssskt#!wm_aid=2a824973ef9342c4be7905c16319f845!!wm_id=0b819558dc244c21a797b7e72a92295b)[8](https://mparticle.uc.cn/article.html?uc_param_str=frdnsnpfvecpntnwprdssskt#!wm_aid=2a824973ef9342c4be7905c16319f845!!wm_id=0b819558dc244c21a797b7e72a92295b)

•  碱性条件（pH > 9）：在较高的pH值下，聚合氯化铝的分解速度加快，可能会降低混凝效果。[⁠⁣ ⁠⁣](https://baijiahao.baidu.com/s?id=1775799879123642298)[3](https://baijiahao.baidu.com/s?id=1775799879123642298)

综上所述，为了确保最佳的水处理效果，建议将聚合氯化铝的应用pH值控制在6.5到7.6之间。
