Introduction of lignosulfonate HS 3804000090
Lignin
Lignosulfonate is a type of natural polymer surfactant. Its capability to reduce the surface tension of aqueous solution depends on its adsorption configuration at the air/liquid interface. The dynamic surface tension, the air/liquid interfacial film properties of lignosulfonate at different solution concentrations, pH values and ionic strengths had been measured in the present work. The results showed that the adsorption equilibrium of lignosulfonate at the air/liquid cannot be achieved in a short period; the diffusion coefficient of lignosulfonate from the liquid to the air/liquid interface decreased with the increasing of pH value, while it increased with the increasing of ionic strength. Lignosulfonate could form soluble monomolecular film at the air/liquid interface, whereas the film was unstable. The stability of lignosulfonate monomolecular film became poor with the increasing of solution concentration, ionic strength and decreasing of pH value. Combining with our previous research results, the adsorption mechanism of lignosulfonate at the air/liquid interface was proposed.
Surfactant molecules contain hydrophobic and hydrophilic groups. When surfactants are dispersed in water, the hydrophobic groups generally adsorb at the air/liquid interface; while the hydrophilic groups remain in the aqueous phase. The adsorption of surfactant molecule at the air/liquid interface leads the reduction of the surface tension of water; while the capability of a surfactant to reduce the surface tension of water is related to its arrangement configuration at the air/liquid interface, and the arrangement configuration depends on the surfactant concentration, pH value and ionic strength of solution, and etc
Lignin is a natural polymeric material that is only less than cellulose in amount, and it is one of the main pollution sources, which coming from waste water in the paper-making factory. Lignosulfonate is a by-product of acidic sulphite-pulping. Unlike lignin, lignosulfonate not only contains hydrophobic groups, such as aromatic and aliphatic groups, but also contains many hydrophilic groups, such as sulfonic, carboxyl and phenolic hydroxyl groups. It is a natural polymeric surfactant that can be widely used as concrete water reducers, coal water slurry dispersants, oil-well dispersants and pesticide dispersing agent. But the surface activity of lignosulfonate is lower without chemical modification. The adsorption configuration of lignosulfonate at the air/liquid interface directly affects its surface activity, but so far there are few reports about the adsorption configuration of lignosulfonate at the air/liquid interface. Gundersen et al. studied the adsorption process of lignosulfonate at the air/liquid interface by Langmuir technique. Their results showed that the concentration of lignosulfonate, pH value and ionic strength of solution affected the adsorption configuration of lignosulfonate at the air/liquid interface, but the researchers did not conclude about in what configuration lignosulfonate adsorbed at the air/liquid interface. Following our previous research, we studied the influence of concentration of lignosulfonate, pH value and ionic strength on the dynamic surface tension and the air/liquid interfacial film properties of lignosulfonate solution, and the adsorption mechanism of lignosulfonate at the air/liquid interface was discussed.
