The resource utilization of phosphogypsum (PG) is the key to promote the green development of the phosphorus chemical industry. The natural environment and public safety are significantly threatened by the enormous volume of PG storage. In this study, Ca and S were successfully recovered from the PG via a multistep precipitation in the NaOH-BaCO system. The alkali solution can be recycled five times, with a first recovery ratio of about 97.9%, and the decomposition ratio of PG remained above 70% after five cycles. In addition, the recovery ratios of Ca and S in PG are 99.9 and 82.5%, respectively. The product of BaSO can be used as a weighting agent for oil and natural gas drilling mud. The BaSO can also be used as wave-absorbing materials, and its reflection loss value reaches 97.8% of the analytical purity BaSO. This work provides a new idea for the efficient recycling of Ca and S in PG with an outstanding application prospect.

This study aims to utilize secondary aluminum dross waste to synthesize Fe-Al layered double hydroxide (Fe-Al LDH) for efficient adsorption of arsenic from drinking water. The synthesis process was based on a multi-step hydrometallurgical approach, in which the aluminum content in the waste was first converted to sodium aluminate. This was followed by the transformation into Fe-Al LDH through a series of processes, including gelation, sol formation, simultaneous precipitation, and aging.

Few studies are concerned with the effect of the conjugat protein on the bioactivities of the abalone gonad polysaccharide (AGP). In this study, a series of treatments, including raw material (female and male) defatting, extraction temperature (25-121 °C), proteolysis, ultrafiltration, and ethanol precipitation, was conducted to investigate the role of the conjugate protein on AGP anticoagulant activity. All AGP extracts significantly prolonged activated partial thromboplastin time (APTT) and thrombin time (TT).

Magnetic solid phase extraction (MSPE) has been widely employed in the isolation and enrichment of antibiotics in complex matrices because it presents various unique advantages over traditional SPE including simple operation, fast extraction procedure, low cost and eco-friendliness. In recently years, magnetic molecularly imprinted nanoparticles (MMINs) containing highly specific recognition performance have been widely used to specific extraction of antibiotics under the format of MSPE. In this connection, recent advances of MMINs in the analysis of antibiotic residues are reviewed.
