Zhang, X. and Jin, R., 2018. Detection of chemical composition of sea water based on Gaussian wavelet. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 17–22. Coconut Creek (Florida), ISSN 0749-0208.

Common methods for detecting the chemical composition of sea water involves tedious procedures, which consumes lots of time, wastes an abundance of solvents, and leads to environmental pollution. Therefore, this paper proposes using the Gaussian wavelet, which denoises the absorption spectrum of water quality detection by using wavelet transforms, analyzes the chemical composition of marine Prorocentrum micans and Skeletonema costatum by using gas chromatography / mass spectrometry (GC/MS), and detects the chemical composition of sea water by using the Flow Injection-Solid-Phase Extraction-Spectrophotometry method. Experimental results show that the proposed method can improve the detection efficiency by 20%.
