In this work, Ammonium Molybdophosphate (AMP) was synthesized and the adsorption of Cs onto it under different initial pH conditions was investigated. The results show the negative effect of the hydronium and hydroxyl irons on the uptake of Cs while the iron-exchange capacity can reach 144.8 mg/g. In addition, the structure differences between AMP samples before and after Cs adsorption were examined by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and Raman technique. The results show that the Keggin structure of AMP stayed unchanged while new bonds arose after the Cs adsorption.
Abstract. The inhibition effect of oleic-based imidazoline (OIM) and mercaptoethanol (ME) on the corrosion of carbon steel in carbon dioxide saturated 3.5% sodium chloride solution was investigated by weight-loss method, electrochemical techniques and scanning electron microscopy (SEM) analysis. Results indicate that compared with individual addition of OIM or ME, better corrosion inhibition effect can be obtained when OIM-ME mixture is added. The OIM-ME mixture can inhibit both anodic and cathodic reactions, significantly alleviating the corrosion of carbon steel. Morphologies analysis also confirms the excellent inhibition effect of OIM-ME mixture. Thus, a conclusion can be drawn that there is notable synergistic inhibition effect between OIM and ME, and the optimal molar ratio of OIM and ME is 1:3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
