Eosin Yellow (EY), an anionic dye (acid dye) was adsorbed using an agricultural waste, pineapple peels (PP) as bio-sorbent in order to investigate its suitability as an alternative adsorbent, and to give insight into the mechanisms of binding. The study i... see more

Dried biosorbent was prepared from Aphanothece sp. cyanobacteria harvested from a photobioreactor system fed with atmospheric carbon dioxide. Cadmium-ion biosorption of the prepared biosorbent from aqueous solution was characterized by non-linear (Langmui... see more

The need to explore an environmentally friendly and cheaper ads­orbent for removal of dye from polluted water has imposed a requirement for thorough thermodynamic studies of dye removal from synthetically polluted water. The sorption capacities of untreat... see more

Adsorption of Cu(II) ions from aqueous solution onto activated carbon (AC) prepared from Pithecellobium jiringa shell (PJS) waste was investigated by conducting batch mode adsorption experiments. The activation with ultrasound assistance removed almost al... see more

The effect of initial Congo Red and Procion Red concentration on isotherm adsorption and thermodynamic adsorption study using natural and Zn/Fe Pillared bentonite have been conducted. The adsorbents were also characterized by Fourier transform infrared (F... see more

Modeling of isotherm and adsorption thermodynamics in this study, leads to the determination of the classification of adsorption isotherms and the determination of the amount of energy and entropy to determine the impeccability of the process. As an adsor... see more

A precious metal such as gold can be obtained from mining. Metals in low concentrations at geothermal sites or in industrial waste are difficult to gain using the conventional mining process. Alternative approaches for recovering metals from dilute soluti... see more

Graphene oxide with eggshells (GO/ES) adsorbent has been studied for fluoride ions (F–) removal. An adsorption study was conducted in batch experiments at different adsorption parameters, which are initial F– concentration, contact time, and temperature. ... see more

Arsenic is a toxic element for human health. It persists in the environment as a result of natural and anthropic contamination, generating nocive effects for consumers. Some of them can be cancer, cardiovascular disorders, hypotension, metabolic disease a... see more
