The effective removal of aniline and its derivatives from wastewater is very important due to the high toxicity. Adsorption with a high-performance adsorbent is an efficient pathway. A novel activated carbon, ACUF-700, was synthesized using homemade ureaformaldehyde resin as the major carbon source carbonized at 700 o C. ACUF-700 is characterized by surface area analyzer, FTIR, elemental analyzer, and SEM. The adsorption properties of ACUF-700 towards anilines are also investigated by using batch methods. The test results showed that the ACUF-700 possesses higher specific surface area and narrower pore size distribution. In virtue of its developed pore structure and nitrogencontaining chemical groups, the adsorption capacities towards aniline, p-toluidine and p-chloroaniline could reach 95.6, 108.1 and 128.9 mg/g, respectively. The adsorption process could be well described by the intra-particle mass transfer diffusion model and Sips model. Besides, ACUF700 was regenerated easily using diluted hydrochloric acid solution as eluent and ACUF700 possesses better reusability.

The presented study investigates the immunity activities of Pleurotus ostreatus polysaccharides (POP) in cyclophosphamide (CTX)-immunosuppressed mice. The CTX-induced mice are orally administrated with POP at the dosage of 100, 200, and 400 mg kg −1 bodyweight respectively, for 28 days. Experimental results show that POP improves the immune functions of the immunosuppressed mice, retards the decrease in body weight and enhances the immune organ index, and simultaneously increases the T-lymphocyte proliferation rate. In the POP group, the level of delayed-type hypersensitivity (DTH), the activity of lactate dehydrogenase (LDH), acid phosphatase (ACP), immunoprotein (Ig-A, Ig-G, Ig-M), cytokines (TNF-𝜶, IL-2, INF-𝜸), blood parameters (red blood cells, hemoglobin, white blood cells, platelets) are also remarkably improved compared to the CTX group. This study shows that POP exhibits significant antioxidant activity by enhancing catalase (CAT), glutathione peroxidase (GSH-PX), total antioxidant capacity (T-AOC), and total superoxide dismutase (T-SOD), and inversely decreasing the malondialdehyde (MDA) levels. In conclusion, it can be proved that the preventive intervention of POP can enhance the immune function and antioxidant activity in the immunosuppressed mice. These findings may provide a valuable reference for the application of POP in chemotherapy-induced immunosuppression therapy.
