TLDR
The interaction and main factor and optimum conditions of the under study process were determined from response surface plots based on desirability function and the maximum CR adsorption were achieved at pH of 4, 15 mg L-1 of CR, 0.017 g of Au-Fe3O4-AC and 5 min sonication which owing to 99.49% removal efficiency is highly recommended for future CR removal from different matrixes.About:

A general kinetic model for adsorption: Theoretical analysis and modeling
Xuan Guo,Jianlong Wang +1 more
TL;DR: Based on the Langmuir kinetics, and the theoretical analysis of the PFO and PSO models, a general form of adsorption kinetic model was developed in this paper, and the experimental data from previous studies and literature were used to fit the mixed-order (MO) model.

Characteristics of nitrogen and phosphorus adsorption by Mg-loaded biochar from different feedstocks.
TL;DR: Herein, biochars from 6 different feedstocks were produced using magnesium chloride (MgCl2) as a modifier due to their sorption behavior toward NH4+-N and phosphorus in an aqueous solution to demonstrate the significant contributions from magnesium and steric effects.

The adsorption of gases on plane surfaces of glass, mica and platinum.
TL;DR: In this article, the absorption index at the wave length of the band maximum was found to be proportional to the total concentration of metal at shorter wave lengths, however, deviations were observed, the absorption increasing more rapidly with concentration than Beers' law would demand.

Kinetics of Adsorption on Carbon from Solution
Walter J. Weber,J. C. Morris +1 more
TL;DR: In this paper, it was shown that the rate of adsorption of persistent organic compounds on granular carbon is quite low and the rate is partially a function of the pore size distribution of the adsorbent, of the molecular size and configuration of the solute, and of the relative electrokinetic properties of adsorbate and adsorbents.
