| الوصف: | A fost studiat procesul de diminuare a concentrației emolientului, acidul 2,2-dihidroximetil propionic (DMPA), în prezența colorantului textil portocaliu activ (PA).S-a constatat că efectul înlăturării componenților din amestecul de colorant şi emolient se măreşte la aplicarea metodei de electroflotare sau electroflotocoagulare, iar la aplicarea metodei de coagulare efectul înlăturării se micșorează. La fel, s-a stabilit că sistemele cu concentraţii mici de colorant PA (100,0 mg/l) şi emolient (20,0-80,0 mg/L) se epurează prin combinarea metodei de electroflotocoagulare şi adsorbţie. Odată cu mărirea concentraţiei compuşilor organici, este necesară combinarea metodelor de electroflotocoagulare şi oxidare.REMOVING ACTIVE ORANGE DYE AND 2, 2-DI-HYDROXYMETHYL PROPIONIC ACID USING CONCENTRATION METHODS IN THE FIRST STAGE FOLLOWED BY OXIDATION AND ADSORPTIONIt has been studied the process of diminishing the concentration of emollient 2,2-dihydroxymethyl proponic acid (DMPA) in the presence of the active orange textile dye (AP).It has been found that the effect of removing the organic components of the dye and thickeners mixture is increased by applying the electrofloating or electrofloatocoagulation method and the removal effect decreases when is applied the coagulation method.Also, it was found that the simulated systems which are low concentrations of dye AP (100,0 mg/L) and the concentrations of the thickener are up 20,0 to 80,0 mg/L) shall be treated by the combination of the electrofloatocoagulation and adsorption methods. If it is increasing the concentration of organic compounds, they are purified by a combination of electrofloatocoagulation and oxidation methods. |
