英文摘要 | Synthesis of high purity ammonium alum crystallized from solutions containing impurities was investigated. It was found that various parameters, including initial Al-2(SO4)(3) concentration, supersaturation, temperature and agitation, have a great effect on the purity of ammonium alum crystals. EDS analysis of crystals indicates that K+ ions were more easily included into ammonium alum crystals than other impurities. Impurities were removed more effectively by non-agitation crystallization than by agitation crystallization. In non-agitation crystallization, the content of K in crystals was drastically decreased and Na, Ca, Mg and Si were almost removed. Ammonium alum crystals with high purity were successfully synthesized by the method of non-agitation recrystallization. Distribution coefficient K-K was much greater than K-Na, which explained that K+ ion was more easily incorporated into ammonium alum crystals than Na+ ion. |
