Abstract

The invention provides a method for performing strontium element enrichment on silk fabric cultural relics. The method comprises the following steps that 1, an appropriate quantity of silk fabrics are taken and soaked in 7 ml-10 ml of a hydrofluoric acid solution HF (aq) with the mass percent of 20%, and ultrasonic treatment is performed for 1-2 h at room temperature; 2, the undissolved silk fabrics are taken out and flushed with deionized water for twice to obtain the remaining silk fabrics; 3, 10 ml-20 ml of an HNO3 solution with the mass percent of 30% and 10 ml-20 ml of a hydrogen peroxide solution with the mass percent of 30% are taken and fully mixed to obtain a solution A; 4, the silk fabric cultural relics obtained in the step 2 are dissolved in the solution A, and static standing is performed at the constant temperature of 30 DEG C for 15 min-1 h to obtain a solution B; 5, the solution B is evaporated to be dry on a heating plate with the temperature of 80 DEG C to obtain a solid C; 6, a few of the solid C is taken and dissolved in an HNO3 solution with the concentration of 3 mol / L to obtain a solution D; 7, separation and enrichment are performed on the solution D through 50-100-mesh SrSpecTM resin quartz columns, and then the resin columns are eluted by taking deionized water as eluent to obtain a solution E. The method has the advantages of being high in sensitivity and specificity and the like.

Description

technical field [0001] The invention relates to a strontium element enrichment method, in particular to a strontium element enrichment method for silk cultural relics. Background technique [0002] Silk is the first global commodity in history, and the source of silk cultural relics has been the research direction of historians and archaeologists for more than a hundred years. Although patterns, styles and weaving techniques were once important methods for judging the origin of silk, none of these methods can provide conclusive evidence for the origin of silk in view of the integration of civilizations. [0003] At present, using strontium stable isotopes to trace the origin of silk fabrics is a more accurate method system for textile cultural relics traceability, and it is also a development direction for scientifically developing textile cultural relics isotope technology traceability. However, the content of strontium in silk cultural relics is very small, and it is diff...
