Adsorption of Cd(II) from acidic aqueous solutions by tourmaline as a novel material

Adsorption of Methylene Blue from Aqueous Solutions by Silk Cocoon ‎

This study concerns the performance of cocoons spun by silk worms as a natural ‎adsorbent for removal of Methylene Blue (MB) from aqueous solutions. To study the adsorption ‎process, the effect of various parameters such as contact time, adsorbent dosage, dye initial ‎concentration, and pH of the solution were investigated. According to the experiments, the kinetic ‎data were best described by ...

Removal of health hazards causing acidic dyes from aqueous solutions by the process of adsorption

Adsorption of copper, lead and cadmium from aqueous solutions by activated carbon prepared from saffron leaves

Background: Industrial development has caused the release of various pollutants including heavy metals into the environment. These toxic compounds are extremely dangerous to living beings and the environment due to their non-biodegradability, severe toxicity, carcinogenicity, the ability to be accumulated in nature and the ability to contaminate groundwater and surface water. The aim of the pre...

Removal of phenol from aqueous solutions by adsorption.

Experiments have been conducted to examine the liquid-phase adsorption of phenol from water by silica gel, HiSiv 3000, activated alumina, activated carbon, Filtrasorb-400, and HiSiv 1000. Experiments were carried out for the analysis of adsorption equilibrium capacities and kinetics. The adsorption isotherm model of the Langmuir-Freundlich type was the best to describe adsorption equilibrium da...

Kinetics adsorption of Amoxicillin from aqueous solution by Graphen Oxide- Gold nanoparticles (GO-AuNPs) nanocomposite as novel adsorbent

In this research, Graphene Oxide- Gold nanoparticles (AuNP/GO) were easily fabricated by a redox reaction between GO and chloroauric acid without using any additional reductant and then used to stabilize Pickering emulsions. (AuNP/GO) was investigated by FT-IR spectroscopy. The changes of parameters such as contact time, pH, Amoxicillin initial concentration and temperature were tested and inve...
