Adsorption behavior of a textile dye of Reactive Blue 19 from aqueous solutions onto modified bentonite
Gök, Özer; Özcan, Asiye Safa; Özcan, Adnan (Elsevier Science BV, 2010)The aim of this study is to evaluate adsorption kinetics, isotherms and thermodynamic parameters of Reactive Blue 19 (RB19) onto modified bentonite from aqueous solutions. The effects of pH, contact time, initial dye ... -
Adsorption kinetics and isotherm parameters of naphthalene onto natural- and chemically modified bentonite from aqueous solutions
Kaya, Erbil Melek Özlem; Özcan, Asiye Safa; Gök, Özer; Özcan, Adnan (Springer, 2013)Polycyclic aromatic hydrocarbons (PAHs) have widely been studied and a special concern because of their mutagenic and carcinogenic activities. In this study, natural- and chemically modified-bentonite were characterized ... -
Adsorption kinetics of naphthalene onto organo-sepiolite from aqueous solutions
Gök, Özer; Özcan, Asiye Safa; Özcan, Adnan (Elsevier Science BV, 2008)In this study, the adsorption kinetics of naphthalene onto organically modified-sepiolite was investigated by means of the effects of pH, contact time, adsorbent dosage and temperature. The modification of natural sepiolite ... -
