A North American manufacturer of stainless steel products sought help on understanding the chemistry of mixtures of concentrated sulfuric and chromic acids, pH < −2. Sabol modeled the system with rigorous simultaneous equilibrium analysis (nine independent aqueous species, including activity coefficients) and recommended adjustment of acid input and waste output streams to produce more consistent metal product and technology for process monitoring. Sabol also supervised installation of an acetylene flame Atomic Absorption Spectrometer and operator training.
