Summary: Catalytic conversion of waste biomass to furfural using hetero-polyacid catalysts supported on H-ZSM-5 zeolite was investigated. The PW12/ZSM-5 catalyst with low PW12 loading showed high efficiency in converting biomass (xylose, xylan, and corn stover) to furfural at moderate temperature (130°C), with yields of 73.3% (xylose) and 75.1% (xylan). The PW12 loading and acid sites distribution were found to be crucial for the catalytic performance. Additionally, the presence of LiBr enhanced the furfural yield due to its Lewis acidity. The PW12/ZSM-5 based solid polyacid catalyst showed promise for efficient furfural production from biomass with high yield and easy separation.

Summary: This research studied the stability and reactivity of green iron oxide nanoparticles (EL-Fe NPs) synthesized from Eucalyptus globulus leaf extract in removing NO3- ions from polluted water. Various characterization techniques were used to analyze the EL-Fe NPs, and the effect of different factors such as contact time, pH, KCl salt, and anions on the adsorption of NO3- by EL-Fe NPs was evaluated. The results showed that EL-Fe NPs had irregular nano-particulate structures and exhibited strong adsorption capacity for NO3- at certain conditions, but the adsorption was influenced by pH, salt concentration, and the presence of phosphate ions.

Summary: In this work, a new dendrimer modified magnetic graphene oxide (GO) was used as a substrate for electrodeposition of Au nanoparticles. The modified magnetic electrode was employed for sensitive measuring of As(III) ion as a well-established human carcinogen. The prepared electrochemical device exhibits excellent activity towards As(III) detection using the square wave anodic stripping voltammetry (SWASV) protocol. At optimum conditions (deposition potential at -0.5 V for 100 s in 0.1 M acetate buffer with pH 5.0), a linear range from 1.0 to 125.0 μgL-1 with a low detection limit (calculated by S/N = 3) of 0.47 μg L-1 was obtained. In addition to the simplicity and sensitivity of the proposed sensor, its high selectivity against some major interfering agents, such as Cu(II) and Hg(II) makes it an appreciable sensing tool for the screening of As(III). In addition, the sensor revealed satisfactory results for detection of As(III) in different water samples, and the accuracy of obtained data were confirmed by inductively coupled plasma atomic emission spectroscopy (ICP-AES) setup. Accounting for the high sensitivity, remarkable selectivity and good reproducibility, the established electrochemical strategy has great potential for analysis of As(III) in environmental matrices.
