p-Aminophenol （PAP）, a typical amphoteric compound, has been widely used as raw chemical material and important interrnediate in various fields. To study on the recovery of PAP, an experimental comparison of the adsorption and desorption properties of PAP onto three types of hyper-cross-linked resins in aqueous solutions was performed. This paper focuses on the static equilibrium adsorption and desorption behaviors, the adsorption thermodynamics, the column dynamic adsorption and desorption, and other influencing factors of adsorption, such as temperature and pH values. All the isothermal data fit well to the Freundlich model. The capacity of equilibrium adsorption for PAP on NG-10 is the highest within the temperature range 288K-318K, which may greatly contribute to the advantage in specific surface area, especially the micropore area, of the adsorbent. While in the desorption experiments, NG-9 achieved relative well regeneration efficiency whether by ethanol or by 4% hydrochloric acid. Furthermore, the results of column tests and field applications were also proved that NG-9 was an effective sorbent for the reclamation PAP from wastewater.

Refractory dissolved organic matter （DOM） from landfill leachate treatment plant was with high dissolved organic carbon （DOC） content. An aminated polymeric adsorbent NDA-8 with tertiary amino groups and sufficient mesopore was synthesized, which exhibited high adsorption capacity to the DOM （raw water after coagulation）. Resin NDA-8 performed better in the uptake of the DOM than resin DAX-8 and A100. Electrostatic attraction was considered as the decisive interaction between the adsorbent and adsorbate. Special attention was paid to the correlation between porous structure and adsorption capacity. The mesopore of NDA-8 played a crucial role during uptake of the DOM. In general, resin in chloride form performed a higher removal rate of DOC. According to the colunm adsorption test, total adsorption capacity of NDA-8 was calculated to 52.28 mg DOC/mL wet resin. 0.2 mol/L sodium hydroxide solution could regenerate the adsorbent efficiently.

OBJECTIVE To evaluate the cardotoxicity from recombinant human endostatin(rh-endostatin)combined with chemotherapy. METHODS A total of 12 cancer patients treated with rh- endostatin combined with chemotherapy were selected,and their clinical data *** symptoms,including cardiopalmus, chest distress,dyspnea and changes in their electrocardiogram (ECG),myocardium enzymogram and left ventricular ejection fraction(LVEF),were observed during the drug *** indicators were used for early diagnosis of cardiotoxicity. RESULTS Compared with a pre-therapeutic value,there was a significant increase in the CK-MB value at one week after starting the treatment as well as at the end of treatment(P<0.05).There was a significant change in the ECG at the end of treatment, compared to a pre-therapeutic condition(P<0.05),but there was no significant difference when comparing the pre-and post- therapeutic LVEF values. CONCLUSION It was recognized that mild cardiac adverse reactions exist in the regimen of recombinant human endostatin combined with *** therapy caused definite injury to the cardiac muscle,but cardiac functions were not obviously ***-MB and ECG may be used as indicators for early monitoring cardiac *** against cardiac adverse reactions should be heightened during a course of rh-endostatin combined with chemotherapy.
