Summary: This study proposed a method to convert homogenized Gracilariopsis lemaneiformis into high-valued neoagarooligosaccharides (NAOs) and dietary fiber simultaneously using an enzyme-assisted one-step process. The NAOs showed potential antioxidant activities and the dietary fiber concentrate had physiological properties that make it promising for use in the food industry. The process was environmentally friendly and preserved the active compounds, providing insights for the comprehensive use of other seaweeds or plants with gel-like polysaccharides.

Summary: This study focused on the impact of 3 key variables (macroalgae mass, water salinity, and Nd(III) initial concentration) on the performance of two living macroalgae in the removal and bioaccumulation of Nd(III), finding optimal operating conditions through Response Surface Methodology (RSM). The results showed that under lower water salinity and higher macroalgae mass conditions, the removal efficiency of Nd(III) was the best.

Summary: In this study, anhydrous calcium sulphate (CaSO4) with low P2O5 and F- contents was prepared from phosphate ore powder by one-step acidification. The sulfuric acid concentration, liquid-solid ratio, and reaction time were optimized to achieve a CaSO4 product with P2O5 and F- contents of only 0.03% and 0.05%. Furthermore, the addition of OA improved the removal of SiO2 impurities, resulting in a final purity of CaSO4 of 96.65%. The study also investigated the mechanism of impurity removal and CaSO4 formation. Overall, this study enhances the yield of H3PO4 and the availability of phosphogypsum, providing a reference pathway to improve the benefits of wet-process phosphoric acid.
