Study of production 500 kg/batch polyaluminum chloride from aluminum

The variation of acid concentration as reactant and reaction time were conducted to determine its effect on the composition of PAC and the amount of gypsum produced. The optimum experiment produced liquid PAC with the highest Al 2 O 3 composition of 11.96% and the lowest Cl ? ion of 10.87% at 2 hours reaction time with a total acid

An alternative method for preparation of polyaluminum chloride

In this research, polyaluminum chloride prepared by the fresh aluminum hydroxide gels was named PAC G that is different from the conventional PAC in terms of composition and characteristic. And its aluminum species distribution was detected by means of Ferron assay, nuclear magnetic resonance (NMR), X-ray powder diffraction (XRD) and scanning electron microscopy (SEM).

In recent years, the preformed polymeric aluminum salts have been used with some success. Polyaluminum chloride (PAC) may be produced by adding base to aluminum chloride until an empirical formula ofAl(OH)nC13-n (with n from 1.0 to 2.5) is achieved. A variety of species can be formed when stock solutions of PAC are added to a raw water.

2.2.4. Characterization of the Produced PAC. The produced PAC solution was dehydrated at 105¡ãC and made powder sample for structure analysis. X-ray diffraction (XRD) was measured for the determination of crystalline phases in solid coagulants using D/max-rA X-ray diffractometer with Cu K radiation in the range of 3¡ã to 80¡ã at a scan rate of

Abstract Aluminum chloride hydroxide, AlCl (OH) 2, AlCl 2 (OH), products, commonly known as polyaluminum chlorides (PAC), are used for a wide variety of industrial applications. Other names for PAC are basic aluminum chloride, polybasic aluminum chloride, aluminum hydroxychloride, aluminum oxychloride, and aluminum chlorohydrate.

Furthermore, instead of PAC components, aluminum chloride and aluminum hydroxide are employed, and their catalytic reaction activity is lower than PAC¡¯s. This indicates that the special polynuclear Al¨CO cation structure of the PAC material plays a key role in the catalytic process (the detailed screening results of reaction conditions are shown in Table S1 ).

Even though aluminum chloride has a higher nominal concentration of chloride than PAC, it should be ion paired at low basicity, as the current was initially limited. The current increased during the first 3 hours until about 30% basicity material and then the voltage started to decrease when the material reached 40% basicity.
