Physicochemical Analysis, Elemental and Amino Acid Composition of Wool and Silk
Abstract:The ash content of wool and silk was determined by burning the corresponding samples. The elemental composition of wool and silk was determined by ICP-mass spectral analysis, 26 macro- and microelements were found. Phosphorus has the maximum content in wool and silk samples, magnesium has the minimum content for wool, and potassium for silk. Chromato-mass spectrometry revealed 17 amino acids in wool and silk samples. Wool is characterized by a high content of phenylalanine, glycine, tyrosine, while silk is cha… Show more
