| Abstract: | The multiple linear regression simultaneous
extractionphotometric method is applied to the rapid determinations of Ca and Mg in water
samples. the principle of method,experimental conditions,regression equations and linear
equations are discussed.Ten of mixed samples and water samples are determined and
satisfactory results are obtained. |
