Rapid determination of trace homogeneous catalyst in chemical production

In the WTG-PLS approach, first, the UV–vis spectrum was decomposed into several sub-signals by WT, and the selected sub-signals with GWO was reconstructed into an effective signal (S); Then the moment variables were calculated from the signal S by TCM method and further selected with GWO algorithm; Finally, PLS was used to establish the quantitative WTG-PLS model.
