The relationship between the moisture content of a certain product and the relative humidity at equilibrium at a given temperature can be expressed by mathematical equations, so-called sorption
isotherms or hygroscopic equilibrium curves (Goneli et al.
The preconcentration was followed in this sorption
method and the concentrations were determined by atomic absorption spectrophotometer.
The experiments were designed to evaluate fast initial sorption
, allowing separate estimation of the end-grain (i.
Roasting also affects the degree of moisture sorption
, with coffee being more (dark roasts) or less (light roasts) hygroscopic according to the degree of roasting (Correa, Oliveira, Oliveira, Vargas-Elias, & Baptestini, 2016b).
of water is known to change material properties by hydro-plasticization  and changes the volume by moisture expansion .
The effect of parameters such as initial concentration of dye, amount of bio-sorbent, initial pH, shaking time and speed were investigated to evaluate its sorption
The greatest sorption
was found for particle size of 200 um with a 0.
Their thermodynamic properties, such as the adsorption enthalpy, DHa, molar evaporation enthalpy, DHv, the sorption

2012) named preferable features of inexpensive and readily available sorbents: fast oil sorption
rate, high oil sorption
capacity, low water pickup, high oil retention capacity during transfer, high recovery of the absorbed oil with simple methods, good reusability, high buoyancy, excellent physical and chemical resistances against deformation, photo-degradation, and chemical attacks.
They cover integrating tunable anion exchange with reverse osmosis for enhanced recovery during inland brackish water desalination, removing boron from water by ion exchange and hybrid processes, a greener and sustainable approach for synthesizing commercially important epoxide building blocks using polymer-supported molybdenum (VI) complexes as catalysts, solid-phase heavy-metal separation with selective ion exchangers: two novel morphologies, separating concentrated ion mixtures in sorption
columns with two liquid phases, and sensing toxic metals using an innovative sorption
During the sorption
assays the commercial diesel oil (S1800) was used and obtained in a Petrobras gas station, in Botucatu, Sao Paulo State, Brazil, as well as the biodiesel produced by Biopar company, in Rolandia, Parana State, Brazil.
