    Biosorption of Remazol Navy Blue dye with Saccharomyces cerevisiae Biomass
    (Kahramanmaras Sutcu Imam Univ, 2012) Korhan, Hamdullah; Halipci, Hatice Nur; Kertmen, Metin; Digrak, Metin
    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.

    Biosorption of Remazol Turquoise Blue dye with Saccharomyces cerevisiae Biomass
    (Kahramanmaras Sutcu Imam Univ, 2012) Halipci, Hatice Nur; Korhan, Hamdullah; Digrak, Metin; Kertmen, Metin
    Dye contaminants pollution caused by a variety of industries negatively affects the environment and threats especially human health. Nowadays, these kind of problems constitute an important place therefore many studies are undertaken only for this purpose. In this study; S. cerevisiae was used to as a biosorbent for removal of Remazol Turkuaz Blue (RTB) 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 RTB adsorption. In optimum pH experiments, it is determined that maximum biosorption was occured at pH 3 value at ratio of % 95.48(30. dk). The optimum conditions for dye concentrations was obtained for 150 mg/L solution and it is indicated that 1 gr yeast could maximum adsorb 61.51 mg /g RTB dye.
