RECOVERY OF REACTIVE COLORANT WITH HYDROTHALCITE AND REUSE FOR PRINTING
In this work, the adsorption capacity of hydrotalcite on the Reactive Yellow 2 textile dye has been verified. Nanoclays are elements with a high capacity for adsorption of dyes and can be reusable as printing pigments. For this, the Lambert-Beer lines of each dye have been previously made. A dye con...

| description | In this work, the adsorption capacity of hydrotalcite on the Reactive Yellow 2 textile dye has been verified. Nanoclays are elements with a high capacity for adsorption of dyes and can be reusable as printing pigments. For this, the Lambert-Beer lines of each dye have been previously made. A dye concentration of 1 g/L and a clay concentration of 3 g/L have been used. Then the dye has been introduced into the clay by stirring for 24 hours in 100 mL of solution of the dye, to later filter it and allow to dry. The adsorption of the dye by the nanoclay has been almost absolute, leaving the initial solution very clean, which are excellent results from the point of view of cleaning wastewater. After drying and collecting the clay, a stamping paste in a substrate of PES/CO 50%/50% was made with the hybrid obtained, using a concentration of 1.5 g/kg and 7.5 g/Kg. They were then heat-set at 180ºC for 30 seconds. Finally, the samples obtained are analyzed on a Minolta CM-3600d reflection spectrophotometer to assess the color achieved. There is a difference in color when comparing the two samples, as expected, the printed sample with higher concentration of hybrid shows a greater intensity of colour. The color difference was calculated and the Kubelka-Munk theory was taken as a reference to make an assessment of the strength of the color obtained. |
