Dye is a type of colorants that are widely used in many industries. Many dyes are toxic in nature with suspected carcinogenic and mutagenic effects that affect aquatic lives and also human beings. Adsorption process is considered as eco-friendly method to remove color from the aqueous solution compared to other established method. In this study, Casuarina Equitifolia leaves were used as an adsorbent. The Response surface methodology (RSM) was employed, using a central composite design (CCD) to optimize the three important variables, i.e., initial dye concentration, pH of the dye solution and adsorbent dosage in order to remove of methylene blue from aqueous solution. From the analysis of variance (ANOVA), the value (>0.8) of the coefficient of determination (R2) was obtained. The optimal condition was established at pH 6.91, 0.1 g adsorbent dosage and 10ppm initial methylene blue concentration. The removal efficiency was found to be 98.80%. From the findings, it shows that Casuarina Equitifolia leaves powder is suitable to be used as an adsorbent in removal of color from aqueous solution.

Good Potential

The release of dyes in form of wastewater causes serious environmental problems such as retards photosynthesis, inhibit growth of aquatic biota by blocking out sunlight and utilizing dissolved oxygen. In this study, activated carbon derived from foxtail palm (Wodyetia bifurcata) empty fruit bunch (EFB) was used as an adsorbent to remove methylene blue in aqueous solution. The preparation process of activated carbon consisted of H2SO4 impregnation followed by carbonization at 300ºC for 24 hours. The optimization adsorption process was carried out using Response Surface Methodology (RSM) via Box-Behnken design. Three important operating variables namely dye concentration, contact time and adsorbent dosage were studied. The optimum conditions obtained were 100 ppm of methylene blue, 13 h of contact time and 2 g of activated carbon with the highest percentage of methylene blue removal of 99.9%. Based on the study, activated carbon derived from foxtail palm EFB showed good potential as an adsorbing agent.
