Abstract: In order to solve the problems of low accuracy and low efficiency of traditional water quality detection methods, this paper proposed a testing method for pharmaceutical water quality of inorganic hybrid nano drugs. Firstly, the SH-3900A water quality detector was used to collect multiple parameters of pharmaceutical water, and then spectral normalisation analysis was used to classify the collected results. Finally, the spectral difference between qualified samples and abnormal samples was determined by probability evaluation method to achieve the detection of pharmaceutical water quality. Experimental results show that the detection accuracy of this method is up to 95%, and the detection time can be controlled within 15 min. At the same time, the maximum value of stability coefficient is close to 0.8, indicating that the application level of this method is high.

Keywords: inorganic hybrid nano drugs; pharmaceutical water; multiparameter acquisition; quality inspection; sample classification.
