Evaluating MTBSTFAderivatization reagents for measuring naphthenic acids by gas chromatography-mass spectrometry
Abstract
Naphthenic acids (general formula CnH2n+ZO2) are found in petroleum and oil sands deposits. Release of these acids to aquatic environments is a concern because of their potential toxicity. Naphthenic acids consist of a complex mixture of carboxylic acids, and estimating their concentrations in environmental samples is a challenge. Two recent reports have described
