Abstract The experimental adsorption equilibrium of Cd(II) onto chitosan (Cd(II)/CS) and methyl orange onto bentonite (MO/Bt) were studied in batch adsorption experiments at room temperature for an initial concentration of 236.5 mg/L for Cd (II) (pH = 5) and 33 mg/L for MO (pH = 3).

On the comparison of pseudo-first order and pseudo-second order rate laws in the modeling of adsorption kinetics [PDF]
In most works in the current literature about liquid/solid adsorption kinetics, the respective abilities of pseudo-first order and pseudo-second kinetics for describing the data are compared. In nearly all cases, it is concluded that the latter surpasses the former.

The use of agro-industrial residues of coffee ( Coffea arabica) for the removal of mercury from water [PDF]
Contamination of water bodies by heavy metals is a continuously growing environmental issue. High concentrations of mercury (Hg) in river waters are a recognized environmental problem, because it is one of the most toxic heavy metal ions as it causes ...

Pseudo-Critical Dynamics in First-Order Transitions [PDF]
Simple arguments are presented about critical-like phenomena associated with first-order phase transitions in systems described by non-conserved order parameters. A mean field theory gives a type of critical phenomena near the spinodal point, which is determined by a "pseudo-free-energy" and a "pseudo-order-parameter".
