Description
Fengbo Zhou, Bo Wu, and Jianhua Zhou present a measurement method in two thousand twenty-four for trace metals in zinc solution. In zinc refining, copper and cobalt must be tracked at tiny levels, but their spectra overlap heavily. Zinc and nickel signals interfere further, hurting standard detection.
Their method applies a wavelet transform to the spectra, which sharpens the copper and cobalt signals and strips background interference. An optimization step picks the best transform scale using two quality indexes. Calibration at zero-crossing points of the sharpened spectra then allows both metals to be read at once. Tests beat two standard methods on error and correlation. The authors say the method suits routine checks in zinc plants.
