    Comparison of cationic dyes (basic orange 2, basic yellow 2 and basic violet 3) removal from aqueous solution using clay as an adsorbent
    (Parlar Scientific Publications, 2019) Farizoglu, Burhanettin; Fil, Baybars Ali; Sozudogru, Onur; Aladag, Erdinc; Kul, Sinan
    The present work aims to investigate the removal of three cationic dyes (Basic Orange 2, Basic Yellow 2 and Basic Violet 3) from aqueous solutions by montmorillonite under various experimental conditions. Cationic dyes were selected Basic Orange 2 (BO2), Basic Yellow 2 (BY2) and Basic Violet 3 (BV3). The effects of pH, initial dye concentration, adsorbent dose, agitation speed and ionic strength, on the removal of dyes were studied. According to the experiments results, it was shown, that maximum removal was achieved in less than 45 min. The results indicate that the montmorillonite can be used as a low cost alternative according to other adsorbents in the removal of dyes from wastewater. The maximum adsorption efficiency levels attained were as follows: 95.849% BO2, 99.562% BY2 and 99.169% BV3 onto montmorillonite at pH: 5.0, 100 mg/L initial dye concentration, 0.75g/L clay dosage, 300 rpm agitation speed, 0 M NaCl ionic strength and 293 K, reaction time of 45 min. © by PSP

    (Springer Int Publ Ag, 2022) Kul, Sinan; Boncukcuoglu, Recep; Torun, Fatma Ekmekyapar; Recber, Zuleyha; Sozudogru, Onur; Aladag, Erdinc
    The electrooxidation process, one of the advanced oxidation processes, is one of the effective treatment processes used in treating various industrial wastewaters. This study investigated the treatment of olive mill wastewater using the electrooxidation process. This study includes the effects of different experimental parameters on chemical oxygen demand and total phenol removal efficiencies in olive mill wastewater. Ti/IrO2/RuO2 mesh plates as anode material and Ti mesh plates as cathode material were used in the study. The effects of stirring rate, dilution factor, pH, type of support electrolyte, the concentration of support electrolyte, and current density on chemical oxygen demand and total phenol removal efficiencies were examined in the experiments using a batch reactor. The study found that the chemical oxygen demand and total phenol removal rates were 96.93% and 100% under optimum conditions, respectively. According to the treatment data obtained, it can be said that olive mill wastewater can be treated by the electrooxidation method and can be proposed as a pretreatment system before entering biological treatment.
