Fig. 5From: Development of an efficient route for combined recycling of PET and cotton from mixed fabrics a Yield of TPA against the NaOH concentration, with and without the addition of BTBAC at 90 °C. b Yield of TPA against different BTBAC concentrations at 80 and 90 °C using 10% NaOH concentration. Both figures are based on data from the small-scale experiments, and the reaction time was 100 minBack to article page
