用碱性电解水和不同pH值的氢氧化钠溶液清洗被牛血清白蛋白（BSA）污染的氧化铝（Al 2 O3）颗粒。在用碱性电解水分批和连续清洁期间BSA解吸的效率和速率取决于溶液pH，即，氢氧离子浓度。预处理BSA污染的Al 2 O3与0.3%（v/v）的气态臭氧显着促进BSA解吸在随后的清洁过程中与碱性电解水，取决于预处理的长度。结果表明，组合使用气态臭氧和碱性电解水（pH 11.7）的清洁效率与单独使用高pH NaOH溶液（pH>13.0）的清洁效率相当。
Alumina (Al2O3) particles fouled with bovine serum albumin (BSA) were cleaned with alkaline electrolyzed water and NaOH solutions of different pHs. The efficiency and rate of BSA desorption during batchwise and continuous cleaning with alkaline electrolyzed water depended on the solution pH, i.e., the hydroxide ion concentration. Pretreatment of BSA-fouled Al2O3 with 0.3% (v/v) gaseous ozone markedly facilitated BSA desorption during subsequent cleaning with alkaline electrolyzed water, depending on the length of pretreatment. The results suggest that the efficiency of cleaning with gaseous ozone and alkaline electrolyzed water (pH 11.7) in combination is comparable to that of cleaning with high-pH NaOH solutions (pH>13.0) alone.
