The effect of temperature on the adsorption of the sodium lignosulphonate (SL) on the surface of the selected plastics as a potential solution for the plastics waste management

The separation of one or a group plastics from mix by flotation technique is an essential topic in plastic waste management. Basis the refers to selective adsorption depressant on surface plastic. Consequently, energy alters. Adsorption lignosulfonic acid sodium salt (SL) selected available stream was studied at different SL concentrations and operative temperatures. Studied were Polyvinylchloride (PVC), acrylonitrile-butadiene-styrene polymer (ABS), polystyrene (PS), polypropylene (PP), polyoxymethylene (POM), polycarbonate PC. Based measured equilibrium capacities ([Formula: see text]), adsorbed surfaces with amounts. Increasing temperature had positive effect above-mentioned parameter. Suitable conformity observed between experimental results predicted values traditional isotherms, Freundlich Langmuir. However, for most plastics, model more suitable than Measured thermodynamic parameters showed spontaneous process along endothermic (except PC) reactions. complete PC all temperatures during process.
