Kinetic analyses on Cr(VI) adsorption by AgNps-DE and PDE, using various models (a); fitting data with a multi-stage intra-particle diffusion model for both AgNps-DE and PDE (b); the assessment of appropriateness of adsorption isotherm models for experimental data, using different models for both AgNps-DE (c) and PDE (d); and Vant’ Hoff model for both AgNps-DE (e) and PDE (f).
