Adsorption of Pb(II) by tourmaline-montmorillonite composite in aqueous phase.

In this study, a tourmaline-montmorillonite composite (TMMs) was synthesized by vacuum sintering to adsorb Pb(II) from aqueous phase. Different sintering temperature and proportion of tourmaline (TM) were first investigated by evaluating the adsorption capacity for Pb(II). The results indicated that the proper sintering temperature of the synthesis process and proportion of TM were 800 °C and 30.

Glucose enhanced the oxidation performance of iron-manganese binary oxides: Structure and mechanism of removing tetracycline.

In this work, iron-manganese binary oxides (FMO) modified with different proportions of glucose addition (FMOCx) by co-precipitation method showed good activity in activating hydrogen peroxide (HO) for tetracycline degradation. The structure and surface characterizations of the FMO and FMOCx were measured by XRD, FTIR, TEM, BET and XPS. With increased glucose addition, FMOCx has more surface functional groups such as -OH and -COOH, particle size decreases, surface area gradually increases, and the ratio of high valence iron and manganese also increases.

Changes of heavy metal fractions during co-composting of agricultural waste and river sediment with inoculation of Phanerochaete chrysosporium.

The effects of Phanerochaete chrysosporium on the bioavailability of multiple heavy metals (Pb, Cd, Cu, and Zn) in river sediments were investigated by co-composting with the agricultural waste. The results showed that the Phanerochaete chrysosporium inoculation can greatly enhance the passivation on Cu, Pb and Cd during 60 days co-composting. The effects in the three metals followed the order: Cu > Cd > Pb.
