Adsorption of Methylene Blue and Reactive Black 5 by Activated Carbon Derived from Tamarind Seeds

One of the most environmentally friendly methods to treat wastewater, especially synthetic dyes, is production activated carbon from agricultural waste. Tamarind seeds were transformed negative-value waste into in order study removal dyes. The particular agro was soaked ZnCl2 for chemical activation increase its surface area and enhance porosity. Physical tamarind done by carbonization process burning at a temperature 300 °C 1 hour cooling 24 hours before washing with HCL activate pore seeds' carbon. effects parameters related adsorption dyes seed carbon, such as contact time, initial concentration, absorbance dosage, pH, studied. experimental data found that on both exhibited Langmuir isotherm which correlation value, R2, 0.9227 (methylene blue) 0.6117 (Reactive black 5). Meanwhile, rate methylene blue (MB) Reactive 5 (RB5) be well fitted pseudo-second-order model. More research needed meet standard effluent dyeing wastewater industrial sector.
