Abstract
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 stabilitcă sistemele cu concentraţii mici de colorant PA (100,0 mg/l) şi molient 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.
It has been studied he process of diminishing the concentration of emollient 2,2-dihydroxymethyl prop onic acid (DMPA) in the presence of the active orange textile dye ( A P ). It has been fou nd that the effect of removing the organic components of the dye and thickeners mixture is increased by applying the electrofloating or electro f loat o coagulation method and the removal effect decreases when is applied the coagulation method. Also, it was fo und that the simulated systems which are low concentrations of dye AP (100,0 mg/L ) and the con cen tra - tions 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 inc reasing the concentration of organic compounds, they are purified by a combination of electrofloatocoagulation and oxidation methods.
