background & aims of the study: p-chloronitrobenzene is a benzoic compound that widely used in many chemical industrials. p-chloronitrobenzene may be absorbed through the skin and is suspected to causing cancer. so, developing an easy method to remove of it from the environment is necessary. equilibrium isotherms and adsorption kinetics of p-chloronitrobenzene onto modified silk waste were stud...
The present work was carried out to evaluate the removal of p-nitrophenol by adsorption onto olive cake based activated carbon having a BET surface area of 672 m²/g. The batch adsorption experimental results indicated that the equilibrium time for nitrophenol adsorption by olive cake-based activated carbon was 120min. The adsorption data was modeled by equilibrium and kinetic models. The pseudo...
In attempts to remove toxic metal lead, distinct types of algae biomass have been scrutinized as alternatives to conventional physicochemical technologies. In this research, the absorption of Lead by nanoalgae Scenedesmus sp. was studied at concentration of10 to 100 mg/L, pH 3 to 8, temperature 15 to 40 °C and exposure time of 10 to 60 minutes)in a batch culture system. The concentration of Le...
Background and Objective: One of the major pollutants for environment is nickel and high concentrations of it cause lungs cancer, nasal and bone sinuses. Thus, for protection human's health and environment, it is necessary to remove excess nickel ions from industrial wastewater. The aim of this study was the evaluation of acorn ashes efficiency for the removal of nickel ions. Materia...
