New type of chelating extraction agent containing phenol wastewater treatment
use curved curved bar in the new stationary phase slices flat ring complexation extraction agent ( QH - 1) Results show that a new type of chelating extraction agent containing phenol wastewater treatment when compared to 1:1 ~ 4:1, centrifugal extraction machine speed is 2500 ~ 4000 r/min, the single-stage extraction efficiency is higher than 95% of phenol, distribution coefficient is as high as 108. 6; And compared with 4. 5:1, the speed of 3000 r/min, the extraction efficiency is above 99%.
load extractant used feed, compared with a 15% NaOH solution according to certain adopts counter-current extraction method, change the extraction series, observe the extraction effect; Extraction series certain conditions, the use of countercurrent extraction way, change the feed, compared to observe the effect of extraction, the process for the new type of chelating extraction agent containing phenol wastewater treatment in NaOH solution extraction process, regeneration efficiency can reach 99%, with a wide operating range, easy regeneration, the treatment effect is good wait for a characteristic.
