Management of solid wastes is considered as an economic and environmental issue in the building stone industry. The current study uses raw and calcined calcareous sludge, generated in the stone cutting factories, in order to remove sulfur dioxide. Sludge characterization has been performed, using X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-d...

Background: Synthetic dyes have several harmful effects on human health as well as aquatic life. In this study, activated carbon (AV-AC), based on Aloe vera leaf shells, was used as a novel agricultural adsorbent, one that is low-cost and available for the removal of Congo red (CR) as a carcinogenic dye from aqueous solutions. Methods: In the batch system, the influence of different paramete...

Adsorption is one of the most promising decolorization techniques in dyeing wastewater treatment. Adsorption techniques for wastewater treatment have become more popular in recent years owing to their efficiency in the removal of pollutants too stable for biological methods. Dye adsorption is a result of two mechanisms (adsorption and ion exchange) and is influenced by many factors as dye/adsor...

Durian peel can be the main contributor to agricultural wastes and becomes an environmental problem when it is discarded into landfill site or even burning it. The average of entire durian fruit weight about 255,353 MT for all over country. loading rate landfills increasing, especially with massive amount size waste that requires a larger space dispose of. Therefore, certainly important utilize...

Hemoadsorption, or hemoperfusion (HP) was introduced by H. Yatzidis in early 1960s [1]. It is an extracorporeal technique that cleanses blood by passing it through an adsorbent column. Active carbon (AC) was the first choice due to its undisputable superiority as an adsorbent over other materials. Although the initial results were very successful, this procedure induced a series of complication...

BACKGROUND Nowadays, removal of heavy metals from the environment is an important problem due to their toxicity. OBJECTIVES In this study, a modified method was used to synthesize chitosan-coated magnetite nanoparticles (CCMN) to be used as a low cost and nontoxic adsorbent. CCMN was then employed to remove Hg(2+) from water solutions. MATERIALS AND METHODS To remove the highest percentage ...
