This study investigated the influence of low molar mass organic acids, acetic acid, tartaric acid and citric acid on Cd2+ and Pb2+ adsorption by goethite and montmorillonite. The added concentrations of Cd2+ in the batch adsorption experiments were 0.04 mmol L−1 and 0.4 mmol L−1...
Thermoplastic starch (TPS) was modified with ascorbic acid and citric acid by melt processing of native starch with glycerol as plasticizer in an intensive batch mixer at 160掳C. It was found that the molar mass decreases with acid content and processing time causing the reduction in melting ...
