“…The purpose of rapid detection cannot be achieved; in addition, there is the XRF method [8] , which is fast but expensive in equipment, limited in popularity and complicated in standard preparation. Microwave digestion and sample dissolution technology [9][10][11] has the advantages of high efficiency, fast speed, simple operation, safety and reliability, and greatly improves the digestion speed. It has been widely used in geology, environment, metallurgy, biology, food, etc.…”

The establishment of a microwave digestion method with the advantages of simple operation and complete digestion to process samples has shown that, high sensitivity, wide linear dynamic range, good precision, fast analysis speed and many other advantages of ICP-AES technology for rapid determination of tricalcium phosphate in bone china. Through the use of different P2O5 content of phosphate rock and kaolin national standard material configuration standard working solution for matrix matching to eliminate matrix interference, the microwave digestion sample processing condition selection, coexisting ion interference, method precision, accuracy, and detection limit tests were carried out. The results showed that the detection limit of the newly established method for tricalcium phosphate is 0.011mg.L-1; the HCl-HNO3-HF-H2O2 mixed acid decomposition system dissolves the best samples; the interference of the test results through the matrix matching coexisting ion pair is small; The relative standard deviation (RSD) is 1.08%~4.64%, and the recovery rate of standard addition is 92.4%~107.9%. The established method has high accuracy and precision; the bone china samples are analyzed and compared with the conventional digestion national standard method The t test method is used to prove that the two methods are not significantly different from the test results.

“…The availability of spectrophotometric instruments and the simplicity of analytical procedure make the procedure very attractive for a wide range of applications. Flow injection analysis served analytical advantages such as rapid response, automation, low cost, simple instruments, high reproducibility and high selectivity that make it possible to determine trace levels of ruthenium in real samples [19][20][21][22][23][24]. This article describes an economical, selective and rapid flow injection method for determination of ruthenium in the river and drinking water and human serum.…”
