Comparative analysis of methods for measuring of phthalic anhydride in industrial emissions

The development of the technologies for poly­ether production on the basis of phthalic compounds has led to necessity of creation of a selective measur­ing techniques of phthalic anhydride for industrial emissions. The analysis of photometric, spectropho­tometric, fluorescent and gas chromatographic meth­ods for quantitative definition of phthalic anhydride is presented in the article.
