METHOD FOR RAPID DETERMINATION OF SULFUR CONTENT IN A PLURALITY OF SAMPLES |
| abstract |
The present invention relates to methods for measuring the sulfur content in a plurality of individual samples of fibers or sulfur-containing articles, comprising: a) contacting a plurality of samples with a solution comprising potassium hydroxide to convert sulfur to potassium sulphate; b) simultaneously and individually combusting the plurality of samples of step a) in an oven at a temperature above 650 ° C to remove substantially all organic materials to produce a plurality of residues; c) dissolving each of the plurality of residues in concentrated nitric acid to form individual residue solutions; and d) analyzing the individual residue solutions with Inductively Coupled Plasma (ICP) emission spectrometry to determine the sulfur content of each sample. |
