Supplementary Materials_A Novel Composite Derived from Quartzite Waste Powder as Adsorbent for Efficient Removal of Industrial Dyes

The supplementary materials include the images of the untreated quartzite powder and the prepared composite; Profile related to physisorption of N2 gaseous isotherms at 77.2 K onto the CQ composite; EDS spectra of the CQ composite before and after adsorption experiments; Graphs related to pH at the point of zero charge (pHpzc) of the CQ composite; Comparative studies related to adsorption capacity of CQ and its individual components; Nonlinear regression curves of the experimental data to the theoretical models of PFO, PSO, Elovich, and Avrami for fractional order; and Performance of experimental adsorption equilibrium replicates for MB and RB5 on CQ under varying temperature conditions.
