Study on effect of toluene-acid treatments of recycled carbon black from waste tyres: physico-chemical analyses and adsorption performance

Recycled carbon black (rCB) produced by pyrolysis has a low value because it contains high levels of impurities, such as sulfur, nitrogen, and oxygen. Various treatments have been proposed using chemicals to purify and improve the properties of rCB. In this study, rCB was treated with toluene (rCB-T...

Various treatments have been proposed using chemicals to purify and improve the properties of rCB.
