摘要：

以海藻酸钙胶囊固定活性炭和血红蛋白,研究了H₂O₂存在下其对水溶液中五氯酚的吸附催化去除作用。讨论H ₂O₂及五氯酚的初始浓度、血红蛋白固定量以及pH等对五氯酚去除率的影响。结果表明,当溶液的pH为7 H₂O₂浓度为8.5×10^-4 mol/L、血红蛋白固定量为6.6×10^-6 mol/L、反应温度为25℃,反应时间为280 min时,五氯酚去除率可达到81.8%,且固定化血红蛋白可被反复使用多次。

Abstract:

Activated carbon and hemoglobin are immobilized in calcium alginate capsules. In the presence ofhydrogen peroxide （H₂O₂），the removal of aqueous pentachlorophenol （PCP） by the adsorption catalysis of hemoglobin has been studied. The effects of the initial concentrations of H₂O₂and pentachlorophenol，the dosage ofhemoglobin immobilized and pH on the removal rate of pentachlorophenol from water are discussed. The results showthat the removal rate of PCP can reach 81.8%,when the solution pH is 7，H₂O₂ concentration 8.5×10^-4 mol/L，thedosage of immobilized hemoglobin 6.6×10^-6mol/L，reaction temperature 25 ℃ and reaction time 280 min. The immobilizedhemoglobin could be used repeatedly for many times.

Key words: pentachlorophenol, hemoglobin, immobilization, calcium alginate
