Biosorption Study of Methylene Blue (MB) and Brilliant Red Remazol (BRR) by Coconut Dregs

Water pollution has become a major issue in many countries, including Malaysia. Malaysia is one of the countries that suffers from this detrimental influence on water resource sustainability. Adsorption been discovered to be cost-effective and efficient method removing contaminants such as pigments, dyes, metal impurities. Many biomass-based adsorbent materials have successfully used for removal dyes aqueous solutions. In study, potential use coconut dregs new biosorbent Methylene Blue (MB) (basic dye) Brilliant Red Remazol (BRR) (acidic was investigated. The effects adsorption time, dosage, pH, initial dye concentration MB BRR were investigated using 2-Level Factorial Design Design-Expert 7.1.5. results indicated amount adsorbed increased with increasing concentration, time. However, both favor different pH process. capacity while decreasing pH. Removal optimum at 11, contact time 240 min, dosage 0.25 g adsorbent, an 50 mg/L. Meanwhile, dye, condition 2, 180 equilibrium data fitted very well Langmuir Isotherm equation giving maximum monolayer high 5.7208 mg/g 3.7636 Dye respectively. This study shows can low-cost biosorbents treatment industrial soon.
