摘要: To provide insight into aluminum speciation in raw and finished water to investigate the factors that can affect it, specific fractions have been isolated analyzed samples from three drinking reservoirs Sardinia (Italy) at outlet of their treatment plants. All plants employed polyaluminum chloride as coagulant. The results demonstrate with aluminum-based coagulant did not increase concentration metal water. Aluminum were quite different More than 80% was particulate form. In dissolved fraction, organic forms present higher concentrations water, while following (coagulation, flocculation, filtration) most inorganic Most Al strongly bound or polymeric colloidal, percentages monomeric ranging 40 62%
