1. Lub hauv paus ntawm polyaluminum chloride (PAC) yog ib qho tseem ceeb qhia, tshwj xeeb tshaj yog rau cov dej haus qib PAC cov khoom. Qhov pib qis dua feem ntau ua rau tus nqi siab dua, thiab cov neeg yuav khoom tuaj yeem kho lawv cov nqi raws li cov chaw tsim khoom tshwj xeeb. Tsis tas li ntawd, lub hauv paus ntawm PAC cov khoom sib txawv nyob ntawm cov khoom siv raw thiab cov txheej txheem tsim khoom, xav kom cov tuam txhab hloov kho. Kev nce qib hauv paus ntawm PAC cov khoom tuaj yeem txhim kho kev lag luam zoo ntawm kev tsim khoom thiab siv. Kev nce qib hauv paus ntawm 65% mus rau 92% tuaj yeem txo cov nqi raw khoom los ntawm 20% thiab cov nqi khiav lag luam los ntawm 40%.
2. Cov ntaub ntawv polymeric tam sim no nyob rau hauv polyaluminium chloride sol feem ntau suav nrog: monomers Al3+, Al(OH)2+, Al(OH)2+, dimers Al2(OH)24+, poly(Al113)[AlO4Al12(OH)24·(1}O) as 1{{1}OH) (1) polyaab ions nrog qib siab ntawm polymerization. Cov ntaub ntawv no tuaj yeem hloov pauv raws li qee qhov xwm txheej, thiab lawv cov qauv tshuaj lom neeg yog [Al2(OH)nCl6-n]m (n yog tus lej ntawm 1 txog 5; m yog qib ntawm polymerization, tus lej, m Tsawg dua lossis sib npaug rau 10). Lub℃ntawm polymerization thiab molecular hnyav tsis tuaj yeem txiav txim siab tam sim no; Lub hauv paus B (B yog qhov sib piv ntawm cov molar pawg ntawm hydroxyl pawg mus rau peb npaug ntawm cov txhuas ions hauv polyaluminum chloride) feem ntau yog siv los ua metric.
