Effect of organic Cr(III) complexes on chromium speciation
Ulucinar, S; Onar, AN (Taylor & Francis Ltd, 2005)Chromium speciation in the presence of organic chromium(III) complexes was investigated using solid-phase extraction. The adsorptions of Cr(VI) and Cr(III) on alumina and pumice powder were studied. Maximum sorption of ... -
FT-IR spectroscopic detection of pesticide after sorption onto modified pumice
Akbal, FO; Akdemir, N; Onar, AN (Elsevier Science Bv, 2000)Organoclays can be prepared by modification of the surface with a cationic surface active compound and used for the immobilisation or separation of non-polar contaminants from polluted waters. in this work pumice is used ... -
Gas chromatographic separation of PCB and OCP by photocatalytic degradation
Karakartal, SM; Aygun, SF; Onar, AN (Elsevier Science Bv, 2005)A photocatalytic degradation method was developed for polychlorobiphenyl (PCB) and organochloride pesticide (OCP) discrimination and quantification. A mixture of Aroclor 1260 and p,p'-DDT was irradiated at 254 nm by UV ... -
Phosphate removal by adsorption
Onar, AN; Balkaya, N; Akyuz, T (Selper Ltd, Publications Div, 1996)Phosphate removal efficiencies of 13 natural pumice rock samples obtained from different regions of Turkey were investigated. Samples with high CaO content had high phosphate adsorption capacity. It is concluded that pumice ... -
Photocatalytic degradation of phenol
In this study photocatalytic degradation of phenol in the presence of UV irradiated TiO2 catalyst and H2O2 was investigated. Effects of TiO2 and H2O2 concentrations and pH on photocatalytic degradation were examined. The ... -
Wet oxidation: a pre-treatment procedure for sludge
Genc, N; Yonsel, S; Dagasan, L; Onar, AN (Pergamon-Elsevier Science Ltd, 2002)Wet oxidation process is specially effective for wastes with a high organic matter which can not be removed by conventional treatment methods. The digested and raw activated sludges of PAKMAYA yeast factory are treated by ...
