A method for the simultaneous determination of diatomite in silicon, aluminum, iron, calcium and magnesium was studied by plasma atomic emission spectroscopy method. The samples were pre-treated with microwave digestion with ICP determination and resulted in terms of oxide. The results showed that 5 elements had a good linear correlation coefficient ( r) of 0. 999 or more, precision ( RSD) was less than 2%, recoveries were between 96% and 106%. The method is stable and reliable, simple operation, small reagent consumption.
