Biosorption of Remazol Navy Blue dye with Saccharomyces cerevisiae Biomass

Developing technology with a growing population and rapid industrialization in the world had been caused environmental pollution as an enormous and increasingly difficult problem of solving. Nowadays, the pollution has become disrupts the balance of nature and it has reached levels that threaten human life. From past to present, as a huge part of the earth - water environment-the pollution have been exposed there more than air and soil. In this study; S. cerevisiae was used to as a biosorbent for removal of Remazol Navy Blue (RNB) by adsorption techniqiue. The effects of contact time, initial dye concentration, solution pH and temperature on biosorption were investigated. As a result of the study, 30 degrees C has been found as optimum for maximum RNB adsorption. In optimum pH experiments, it is determined that maximum biosorption was occured at pH 3value at ratio of, and ratio of % 96,56 (30. dk) for RNB. The optimum conditions for dye concentrations was obtained for 150 mg/L solution and it is indicated that 1 gr yeast could maximum adsorb 73,42 mg/g RNB dye.
