Evaluation of diazepam adsorption in aqueous media using low-cost and natural zeolite: equilibrium and kinetics.

Diazepam has been detected in water sources around the world affecting the quality of drinking water. Even in small quantities, recent studies have proven the negative effects of the drug on human body. Since traditional water and sewage treatment do not remove this type of contaminant, it became interesting to evaluate forms to remove them from water sources.
