TL;DR: In this paper, the authors present a review of the state-of-the-art in isotherm modeling, its fundamental characteristics and mathematical derivations, as well as the key advance of the error functions, its utilization principles together with the comparisons of linearized and nonlinearized isotherms models have been highlighted and discussed.

TL;DR: The findings revealed that various parameters, such as the initial pH of the solution to be degraded, oxidizing agents, temperature at which the catalysts must be calcined, dopant(s) content and catalyst loading exert their individual influence on the photocatalytic degradation of any dye in wastewaters.

TL;DR: Two simplified kinetic models including pseudo-first-order and pseudo-second-order equation were selected to follow the adsorption processes of methylene blue and the kinetic parameters of this best-fit model were calculated and discussed.

TL;DR: Coconut husk-based activated carbon was shown to be a promising adsorbent for removal of methylene blue from aqueous solutions and was found to follow closely the pseudo-second-order kinetic model.

TL;DR: In this paper, an abundant agricultural byproduct in Malaysia, was used to prepare activated carbon by physiochemical activation method, and the adsorption capacity was found to increase with increase in the three parameters studied.
