Abstract
One of the most environmentally friendly methods to treat wastewater, especially synthetic dyes, is the production of activated carbon from agricultural waste. Tamarind seeds were transformed from negative-value waste into activated carbon in order to study the removal of synthetic dyes. The particular agro waste was soaked in ZnCl2 for chemical activation to increase its surface area and enhance its porosity. Physical activation of tamarind seeds was done by the carbonization process by burning at a temperature of 300 °C for 1 hour and cooling for 24 hours before washing with HCL to activate a pore surface for the tamarind seeds' carbon. The effects of parameters related to the adsorption of the dyes by tamarind seed activated carbon, such as contact time, initial concentration, absorbance dosage, and pH, were studied. The experimental data found that adsorption on both synthetic dyes exhibited a Langmuir isotherm in which the correlation value, R2, was 0.9227 (methylene blue) and 0.6117 (Reactive black 5). Meanwhile, the rate of adsorption for methylene blue (MB) and Reactive black 5 (RB5) by tamarind seed activated carbon was found to be well fitted in a pseudo-second-order model. More research is needed to meet the standard effluent of dyeing wastewater from the industrial sector.
Highlights
In vision 2020, Malaysia needs rapid development in order to move towards becoming a developed nation
Both synthetic dyes were effectively removed from aqueous media by tamarind seeds' activated carbon
The isotherm data showed a better correlation with the Langmuir isotherm model than the Freundlich isotherm model
Summary
In vision 2020, Malaysia needs rapid development in order to move towards becoming a developed nation. One of the factors in achieving the vision is technology developed in the industries.Such developed technology is in the textile industry and dyeing processes. That rapid development, especially in the dyeing industries, would have a negative impact on the environment. This is due to the current situation, where water pollution has become a major phenomenon. The dyeing wastewater typically contains high concentrations of chemicals and colors.The improper treatment and bad management of textile wastewater would cause environmental problems [2]. A very effective method is needed in order to treat the wastewater from the dyeing textile industries
