Evaluating the possibility of removing Ni2+ ion from aqueous solution by artificial stone

Abstract

Artificial stone is the product created from the recycling technology of glass bottles and jars in Japan with its non-toxic, non-corrosive properties, so this product is considered an environmentally friendly product and used in many projects in Japan such as planting trees, agricultural projects, construction, etc.The article presents the assessment results of removing Ni(II)ion from aqueous solution using artificial stone. The research demonstrated that the Ni(II)ionadsorption capacity of artificial stone in aqueous solution was very high with 5 mg/g in 15-minute contact time condition. In addition, artificial stone was also capable of increasing pH value from the acid medium (pH < 7) to the neutral medium (pH = 7).
