Abstract


Cercetările de laborator au fost realizate pe sisteme model ce conţin coloranţi textili drept componenţi de bază, iar în calitate de compuşi auxiliari – agenţi de dispersie şi etilenglicol. În rezultatul cercetărilor ştiinţifice s-a constatat că efectul înlăturării amestecului de coloranţi şi dispersanţi din sistemele studiate depinde de dimensiunile şi sarcina particulelor de coloranţi, de natura şi concentraţia coloranţilor, dispersanţilor şi a polialcoolilor. De asemenea, epurarea apelor depinde de timpul de electroflotare şi de concentraţia ionilor de aluminiu.

REMOVING THE MIXTURE OF DYES AND DISPERSANTS BY APPLYING THE METHODS OF COAGULATION-ELECTROFLOATATION, AND ADSORBTION

Laboratory researches have been realizing on model systems containing textile dyes as basic components, and as auxiliary compounds were used dispersing agents, and polyalcohol. As a result of scientific researches has found that the effect of removal depends on both, the dyes size and the particle charges, as well as the nature, concentration of dyes, dispersants and polyalcohol. Also, wastewaters depend on the time of electro-floatation and the concentration of aluminum ions.


Keywords


coagulation-electrofloatation, reactive dyes, direct dyes, dispersing agents, wastwaters.
