Summary: This study investigated the photocatalytic performance of Ni-based LDHs in degrading TC, a model antibiotic pollutant. The prepared LDHs showed superior efficiency in eliminating TC from aqueous solution under UV-vis light irradiation, depending on catalyst dosage and TC concentration. The proposed photocatalytic degradation mechanism suggests that superoxide and hydroxyl radicals play a major role in the process.

Summary: The research found that the degradation of tryptophan (Trp) induced by UV follows a pseudo first-order reaction kinetic model, mainly caused by direct UV degradation. The apparent rate constant k(obs) decreases with increasing initial Trp concentration, while increases with rises in pH and temperature. Anions in water have a significant influence on the degradation of Trp, with HCO3- and NO3- contributing to the k(obs) of Trp, but Cl- inhibiting the degradation rate.

Summary: A highly sensitive and selective method for the determination of organophosphorus pesticides was developed using silver nanoparticles modified with graphitic carbon nitride. The method was based on the fluorescence intensity and absorbance changes induced by the catalytic hydrolysis of acetylthiocholine and the inhibitory effect of pesticides on enzyme activity. The method was successfully applied to the analysis of parathion-methyl in real samples.

Summary: Ag3PO4 was prepared for the degradation of tetracycline hydrochloride in UV-vis-LED array. The study found that the integral area was linearly related to the photon flux, and the photonic efficiency oscillated as the integral area increased. Superoxide radicals were identified as the main active species. Furthermore, a dependence model for optimizing photonic efficiency was developed.

Summary: Chlorine dioxide was produced by the reduction of chlorate with hydrogen peroxide in strongly acidic media. UV spectra were acquired to monitor the chlorate reduction process. The study found a linear relationship between the amount of limiting reagent consumed and the maximum height of the absorption peak at 360 nm, allowing for calculations of the maximum amount of chlorine dioxide formed. Results showed efficient formation of chlorine dioxide with high reproducibility.

Summary: A magnetic dispersive micro-solid-phase extraction method was developed for extracting lead (II) and cadmium (II) ions efficiently. The method utilized optimized factors such as desorption and dispersing solvents, extraction and desorption times, sample solution volume, sorbent amount, and pH of the solution to achieve linear calibration curves for the determination of the ions. The method showed low detection limits, good relative standard deviations, and excellent recovery rates when applied to real water samples.
