TLDR
It was concluded that the rice husk column can remove CR from solution andThomas model was found suitable for the normal description of breakthrough curve at the experimental condition, while Adams-Bohart model was only for a initial part of dynamic behavior of the rice Husk column.About:

Cationic and anionic dye adsorption by agricultural solid wastes: A comprehensive review
TL;DR: In this paper, the use of agricultural solid wastes to remove two classes of dye, cationic and anionic dyes, was discussed and a simple comparison among cationi-and anionic dye adsorption by the same adsorbent was made, thus possibly opening the door for a better understanding of the dye-classified adaption process.
Journal ArticleDOI
Adsorptive removal of antibiotics from water and wastewater: Progress and challenges.
TL;DR: The efficiency for removing antibiotics from water and wastewater by different adsorbents has been evaluated by examining their adsorption coefficient (Kd) values, and the future research challenges on process integration, production and modification of low-cost adsorptive materials are elaborated.

Adsorption of dye from aqueous solution by cashew nut shell: Studies on equilibrium isotherm, kinetics and thermodynamics of interactions
P. Senthil Kumar,S. Ramalingam,C. Senthamarai,M. Niranjanaa,P. Vijayalakshmi,Subramanian Sivanesan +5 more
TL;DR: In this article, the effect of pH, adsorbent dose, initial dye concentration, time and temperature on adsorption was studied and the results indicate that Cashew Nut Shell (CNS) can be employed as a low cost alternative compared to other commercial adsorbents in the removal of dyes from wastewater.

Non-conventional low-cost adsorbents for dye removal: A review
TL;DR: It is evident from a literature survey of about 210 recent papers that low-cost sorbents have demonstrated outstanding removal capabilities for certain dyes, and chitosan might be a promising adsorbent for environmental and purification purposes.

Sorption of dye from aqueous solution by peat
Yuh-Shan Ho,Gordon McKay +1 more
TL;DR: In this paper, the sorption of two dyes, namely Basic Blue 69 and Acid Blue 25 onto peat has been studied in terms of pseudo-second order and first order mechanisms for chemical sorption as well as an intraparticle diffusion mechanism process.

Application of biosorption for the removal of organic pollutants: a review
TL;DR: In this article, a review examines a wide variety of microorganisms (fungi, yeasts, bacteria, etc.), which are capable of uptake of organic pollutants, discusses various mechanisms involved in biosorption, discusses the effects of various parameters such as pH, temperature, concentrations of organic pollutant, other ions, and biomass in solution, pretreatment method, etc.

Use of cellulose-based wastes for adsorption of dyes from aqueous solutions.
TL;DR: Based on the adsorption capacity, it was shown that banana peel was more effective than orange peel and intraparticle diffusion of dyes within the particle was identified to be rate limiting.
