Abstract
Methods are provided for determining the surface fatty acid content in a wood pulp or whitewater sample. The methods comprise reacting free fatty acids which are present on the surface of the wood pulp fibers in the sample or in the whitewater with one or more reagents to form a measurable species, and determining the fatty acid content from the quantitative measurement of the measurable species. The method is useful as a quick, portable, accurate and low cost assay for assessing the fatty acid content present at various sample points in pulp and paper mills. The method for determining the free fatty acid content can be conducted in a batch process (e.g., where samples are collected periodically and the test is conducted offline). Alternatively, the method for determining the free fatty acid content can be conducted in a continuous or semi-continuous process (e.g., online sampling/analysis).
