Abstract:

The use of low cost, locally available, highly efficient and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from waste water. This study investigates the potential use of banana peel for the removal of methyl red dye from simulated waste water. The effects of different system variable, adsorbent dosage, initial dye concentration, P^H and contact time were investigated and optimal experimental condition were ascertained. The results showed that as the amount of the adsorbent increased, the percentage of dye removal increased accordingly. Optimum PH value dye adsorption was 2. Maximum dye was sequestered within 100 min of the start of every experiment. The maximum removal of methyl red was obtained at P^H 2 as 88.8% for adsorbent dose of 1 g/100 ml and 100 mg/ L initial dye concentration at room temperature. Banana peel can be an attractive option for dye removal from diluted industrial effluents since test reaction made on simulated dyeing wastewater showed better removal percentage of methyl red.
