摘要：In this study, we performed fractional partition and determination of metals in river water by filtering the sample through a membrane filter with pore size of 0.22 μm immediately after sampling. We considered that the total amount of metal was contained in the nonfiltered sample, and fractional determination was performed separately using atomic absorption spectrometry of the metal in both the filtered and nonfiltered samples. The results showed a different pattern of aluminum distribution compared with other elements.
