皮革水萃取液pH值测定影响因素的探讨

摘要

The effects on determination of pH value in leather aqueous extract were discussed from the selection of pH meter, size of snipped sample,measuring time, filtering methods,concussion rate, extraction water and matters needing attentions. Results showed that the selection of pH meter, the sample size and the measuring time are of great influences on the measurement results of the pH value; while the filtering mode, the oscillation rate and the extraction water are not significant.%从pH计的选择、试样大小、测量时间、过滤方式、震荡速率、萃取用水、测量pH值的注意事项七个方面，较全面地探讨了皮革制品pH值测试的影响因素。结果表明：pH计的选择、试样大小、测量时间对pH值测定结果的影响很大；而过滤方式、震荡速率、萃取用水对于试样的pH值影响不显著。
