Deconvolution of the measured spectra

I have no experience with the process of deconvolution, can anyone help me to do deconvolution of individual measured data (11 individual samples).

For each type of lignins, a stock solution was prepared by dissolving lignin powder in NaOH (0.1 M). UV-VIS absorption spectra were registered using solution of lignin on a CECIL spectrophotometer, absorption region 200 -450 nm, scan speed 5 nm/s and resolution 1 nm. Measured values of absorbance were normalized by absorption maxima for even samples, respective.
