The influence of humic acid,sodium lignosulphonate and new expander on electrochemical characteristics of lead electrode was studied by the cyclic vlotammetry technique.

A green corrosion and scale inhibitor GCL2 without phosphorus was prepared from sodium lignosulfonate by pre oxidation, graft copolymerization and chelation.

In this paper,the scale inhibition and dispersion effects of sodium lignosulfonate (Chinese red pine) on calcium carbonate and its corrosion inhibition to iron are determined and studied.

To gain more understanding of the organic expander performance in negative plate analysis was made for the amount of lignosulphonate left in the negative plate of lead-acid battery with UV-Visible Spectroscopy.

There is a great difference in performance between lignosulphonate and humic acid.

In this paper,the function of each composition of negative expander is reviewed briefly,and the mechanism and application of organic expander lignosulphonate and humic acid are emphasised.

By sulfonation and fasculation reaction,sodium lignin sulfonate was modified as a dispersant(GCL3S) of coal water slurry(CWS).

The water soluble dispersant agent, which the backbone was sodium cellulose sulfate and sodium lignin sulfonate, was prepared using cane dregs and fuming sulfuric acid as raw material .

By the idea of green manufacturing and green products, modified lignin polymer with a new structure were designed and synthesized using the thesis industry by-products– sodium lignin sulfonate through an experiment and also was discussed its application performance in the paper,.
