  • Tannin extracts from the bark of Acacia mearnsii and wood of Schinopsis balansae , commonly known as Quebracho , were employed. These were modified at laboratory sale via the Mannich aminomethylation with formaldehyde and dimethylamine hydrochloride. Some reaction conditions were varied, namely the formaldehyde dosage and reaction time, while keeping the Mannich solution activation time constant, and their influence on the shear viscosity of the created bio-coagulants was evaluated. The effect… CONTINUE READING
