Problems solved by technology

However, these methods have the following disadvantages: the analysis of various elements of Al, Cu, Mn, P and Si needs to prepare the solutions of each element separately, and cannot be jointly measured, which makes the operation complicated and cumbersome, the steps are lengthy, time-consuming, labor-intensive, and efficient. Low, and the use of harmful chemical reagents in the analysis process affects the health of operators and causes secondary pollution to the environment

But the correlation coefficient of the element standard curve that this invention obtains in its detection process is generally on the 0.999 level, can not meet the requirement that the correlation coefficient of each element standard curve expected in chemical analysis is all above 0.9999, so need to further improve the accuracy of the method degree and accuracy
