Lead in cream of tartar, tartaric acid, and citric acid

Leaching of Lead and Zinc from a Low-Grade Oxide Ore in Citric Acid Media

Leaching of a low-grade lead and zinc oxide ore was studied by an organic reagent, citric acid. The quadratic mathematical models were developed for the relationship among the influential parameters and lead and zinc recoveries. Leaching rate was strongly affected by the interactive effects of factors. It was also found that the quadratic effects of stirring speed and linear<e...

Destructive effects of citric acid, lactic acid and acetic acid on primary enamel microhardness

  Objective: This study aimed to assess the destructive effects of citric acid, lactic acid and acetic acid produced from the fermentation of foods on primary teeth enamel.   Methods: This in vitro, experimental study was conducted on 24 sound primary teeth. The teeth were polished with a fine abrasive paper under running water. Tooth pieces measuring 3 × 4 × 3mm were cut out of the teeth and s...

Significance of urinary tartaric acid.

Tartaric Acid Dehydrogenase Activity in Higher Plants1,2

Although the tartrates have been considered as possible metabolites in higher plants since the initial work of Pasteur in 1848, surprisingly little is known of their actual physiological significance. Vickery and Palmer (35) have briefly reviewed the history of (+)-tartrate in plants, including the problems of identification and of nomenclature. They conclude that (+)-tartrate is an uncommon pl...

Citric acid production.

Citric acid is a commodity chemical produced and consumed throughout The World. It is used mainly in the food and beverage industry, primarily as an acidulant. Although it is one of the oldest industrial fermentations, its World production is still in rapid increasing. Global production of citric acid in 2007 was over 1.6 million tones. Biochemistry of citric acid fermentation, various microbia...
