Equilibrium, Kinetics, and Thermodynamics of Methylene Blue Adsorption by Pine Tree Leaves
TL;DR: In this paper, the adsorption capacity of pine tree leaves for removal of methylene blue (MB) from aqueous solution was investigated in a batch system and the effects of the process variables, such as solution pH, contact time, initial dye concentration, amount of adsorbent, agitation speed, salt concentration, and system temperature on the adorption process were studied.

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.

Adsorption of methylene blue on low-cost adsorbents: A review
TL;DR: It is evident from a literature survey of about 185 recently published papers that low-cost adsorbents have demonstrated outstanding removal capabilities for MB, and these include agricultural wastes, industrial solid wastes, biomass, clays minerals and zeolites.
