| Abstract: | The chemical stability of Vanisperse-A sodium lignosulphonate in the electrolytic enviroment simulating the floating charge of lead-acid battery was studied.The UV-Vis and FT-IR spectra were used to analyse the changing situation of some functional groups in sodium lignosulphonate molecule.The results showed that the main functional groups of sodium lignosulphonate such as sulphonic acid group,carboxy group and methoxy group were changed in the acid and reduction environment of battery cathode. |
