AI Article Synopsis
- * The treatment did not alter the functional groups of the polysaccharides but did change their monosaccharide composition and morphology, enhancing their anti-photoaging properties.
- * The most effective polysaccharide, DSFP-45, significantly increased cell viability and collagen production while reducing inflammatory cytokines in UVB-irradiated human skin cells, indicating potential for new anti-photoaging drugs or functional foods from seaweed.
Article Abstract
The high molecular weight and poor solubility of seaweed polysaccharides have limited their function and application. In this study, ultraviolet/hydrogen peroxide (UV/HO) treatment was used to prepare low-molecular-weight seaweed polysaccharides from . The effects of UV/HO treatment on the physicochemical properties and anti-photoaging activity of polysaccharides were studied. UV/HO treatment effectively degraded polysaccharides from (DSFPs), reducing their molecular weight from 271 kDa to 26 kDa after 2 h treatment. The treatment did not affect the functional groups in DSFPs but changed their molar percentage of monosaccharide composition and morphology. The effects of the treatment on the anti-photoaging function of polysaccharides were investigated using human epidermal HaCaT cells . DFSPs significantly improved the cell viability and hydroxyproline secretion of UVB-irradiated HaCaT cells. In particular, DSFP-45 obtained from UV/HO treatment for 45 min showed the best anti-photoaging effect. Moreover, DSFP-45 significantly increased the content and expression of collagen I and decreased those of pro-inflammatory cytokines, including interleukin-1β, interleukin-6, and tumor necrosis factor-α. Thus, UV/HO treatment could effectively improve the anti-photoaging activity of polysaccharides. These results provide some insights for developing novel and efficient anti-photoaging drugs or functional foods from seaweed polysaccharides.

Accelerated transformation of sodium dodecylbenzene sulfonate surfactant in the UV/chlorine process: Kinetics and formation of chlorinated disinfection by-products.

The degradation kinetics of Sodium dodecylbenzene sulfonate (SDBS) surfactant in the UV/chlorine process was comprehensively investigated, and the formation of chlorinated disinfection by-products (Cl-DBPs) were determined. Results showed that the degradation of SDBS by UV, chlorine and UV/chlorine all followed pseudo-first-order kinetics. The rate constant by UV/chlorine in ultrapure water was approximately 3 times higher than the sum of those by UV and chlorine, and decreased from 0.

Article Synopsis
- The study investigates how different UV doses affect the breakdown of carbamazepine (CBZ) in wastewater, specifically using UV-C radiation and hydrogen peroxide (HO).
- It finds that higher UV intensity leads to a faster degradation rate of CBZ, with over 95% removal occurring within 4 minutes when an optimal HO dose is applied.
- The research suggests that adding HO in a wastewater treatment process could improve CBZ removal, predicting over 60% degradation during UV disinfection in treatment plants.
Optimization of UV/HO and ozone wastewater treatment by the experimental design methodology.

The objective of this study was to optimize UV/HO and ozonation systems by means of an experimental design using as a response the efficiency of the operational conditions to remove the methylene blue (MB) dye. Two classes of experimental planning were used: the Doehlert matrix (DM) and the central composite design (CCD). The most important variables for each process were hydrogen peroxide concentration, the ratio of illuminated volume/total volume of the reactor and recirculation flow rate for UV/HO, and ozone flow rate, consumed ozone and MB concentration for the ozonation.
