Yabani kuşburnu ağacı talaşının sodyum hidroksit impregnasyonuyla elde edilen aktif karbon kullanılarak kinolin sarısı boyar maddesinin sulu çözeltilerden giderimi.

In this study, wild rosehip tree shavings that can be grown in Van and its region were used in the production of activated carbon. In the production of activated carbon, wild rosehip wood sawdust (raw material) was impregnated with NaOH (sodium hydroxide) at a ratio of 1:1 and pyrolyzed at 800 ℃ in a nitrogen gas environment. The Langmuir surface area of the produced activated carbon was found to be 1564.3621 m2/g. The adsorption of quinoline yellow, a cationic dyestuff, which is also used in food production as an adsorbed substance, at temperature, concentration and natural pH (pH:6.02) was investigated. Maximum quinoline yellow adsorption was determined by the produced activated carbon and its compatibility was observed according to Langmuir, Freundlich, Temkin and D-R adsorption isotherm models. It was found to be compatible with the Langmuir adsorption isotherm with R2=0.996. As a kinetic model, The compatibility of the pseudo-first-order kinetic model, pseudo-second-order kinetic model, elovich and interparticular kinetic models was examined and it was determined that adsorption was compatible with the pseudo-second-order kinetic model. In the study, concentration measurements were made with UV spectrophotometer. The highest adsorbed value in the adsorption equilibrium data was found to be 245.6885 mg/g. It is thought that the produced activated carbon can be used for dye removal from aqueous solutions. [ABSTRACT FROM AUTHOR]
