Abstract

We developed a filter method with X-ray fluorescence spectroscopic analysis on suspended matter in water. Analyzed elements are SiO2, TiO2, Al2O3, FeO, MnO. MgO, CaO, Na2O, K2O, P2O5 and S. The standard material is a natural altered tuff, which was suspended in water and filtrated under reduced pressure. The accuracy, the standard deviation and the lower limit detection qualify this method. This method is conveniently quick and applicable to the chemical analysis of suspended matter in water.
