Abstract

Isotherms were recorded for the adsorption of chicken egg lysozyme and bovine serum albumin (BSA) on MFI zeolites with different concentrations of acid sites (from 15 to 1000 μmol/g). The maximum adsorption capacities were evaluated, and the correlation between acid site concentration and protein adsorption capacity was identified. The sample with the highest acidity exhibited the highest adsorption capacity. The protein adsorption reduced the total acid site concentration by 20–30% and simultaneously increased the relative content of weak sites. Furthermore, the adsorption affected the IR spectra of the proteins.

MFI沸石酸性对蛋白质吸附的影响

记录了不同酸位点浓度（15 ~ 1000 μmol/g）的MFI沸石对鸡蛋溶菌酶和牛血清白蛋白（BSA）的吸附等温线。评价了最大吸附量，并确定了酸位点浓度与蛋白质吸附量的相关性。酸度越高，吸附量越大。蛋白质吸附使总酸位点浓度降低了20-30%，同时增加了弱位点的相对含量。此外，吸附影响了蛋白质的红外光谱。

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.
