Preconcentration of Cd(II) by chemically converted graphene sheets adsorbed on surfactant- coated C18 before determination by flame atomic absorption spectrometry (FAAS)

A simple, highly sensitive, accurate and selective method for determination of trace amounts of Cd(II) in water samples is presented. A novel chemically converted graphene sheets (CCG) solid-phase extraction adsorbent was synthesized by CCG sheets. The stability of a CCG especially in concentrated hydrochloric acid was studied which used as a recycling and preconcentration reagent for further uses of CCG. The method is...

Inhibition of mild steel corrosion using Juniperus plants as green inhibitior

The corrosion inhibition of mild steel in H2SO4 solution in the presence of Juniperus  plant at a temperature range of 30 to 60°C was studied using chemical (HE and WL) and electrochemical (PDP and EIS) methods. The Juniperus plant acts as an inhibitor in the acid environment. The inhibition efficiency increases with increase in inhibitor concentration but decreases with an increase in temperature. The...
