| 摘 要： | Polyaluminum chloride (PAC) coagulant has been developed and widely used in water and wastewater treatment industry since the 1980s[1]. PAC is normally made by partial hydrolysis of acid aluminum chloride solution using slow alkaline titration method. However, this method would result in many different Al species. Among these Al species, it seems that tridecamer (Al13O4(OH) 724 , often denoted by Al13) is the most effective and stable polymeric Al species for water and wastewater treatme…

| Abstract: | A polyaluminum chloride (PAC) sample was prepared using a slow alkaline titration method. The Bio-Gel P-100 gel column chromatographic technique was used to separate and char- acterize the various forms of aluminum present in the prepared PAC solution. The effluents from a gel column were monitored using online chemical method: Al-Ferron timed complexation spectropho- tometry and by 27Al nuclear magnetic resonance (NMR) spectroscopy. Effects of different experi- mental conditions such as eluent flow rate, ionic strength and pH on separation of Al13 were investi- gated. Experimental results indicated that molecule size exclusion was not the only parameter af- fecting the column chromatographic separation efficiency of Al13 but molecule charge as well. Re- ducing the eluent flow rate, increasing the ionic strength and suitable pH resulted in increase in the separation efficiency. Experimental results clearly indicated that by varying the experimental condi- tions, it is possible to produce pure Al13 species using a gel column chromatographic technique. |
