Abstract

The kinetics of the adsorption of lysozyme and bovine serum albumin (BSA) onto zeolites of BEA and MFI structural types and onto silica adsorbents of the same structural types was studied. The rate constants of the reversible adsorption step were calculated. The adsorption rate constants are 0.4–0.8 L mol^–1 s^–1 for lysozyme and 0.7–1.4 L mol^–1 s^–1 for BSA. The rate constants of the desorption from the surface of all the samples are in the range from 1.3 × 10^–5 to 1.6 × 10^–5 s^–1 for both enzymes.

溶菌酶和牛血清白蛋白在 BEA 和 MFI 结构类型的沸石上的吸附动力学关系

研究了溶菌酶和牛血清白蛋白（BSA）在 BEA 和 MFI 结构类型的沸石以及相同结构类型的二氧化硅吸附剂上的吸附动力学。计算了可逆吸附步骤的速率常数。溶菌酶的吸附速率常数为 0.4-0.8 L mol-1 s-1，BSA 的吸附速率常数为 0.7-1.4 L mol-1 s-1。两种酶从所有样品表面解吸的速率常数范围为 1.3 × 10-5 至 1.6 × 10-5 s-1。

期刊介绍： Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
