PbSO4 Leaching in Citric Acid/Sodium Citrate Solution and Subsequent Yielding Lead Citrate via Controlled Crystallization

Lead citrate is a key precursor for the green recycling of spent lead acid battery paste in a citric acid/sodium citrate (CA/SC) solution. In this study, the main paste component, PbSO4, was leached and crystallized to yield lead citrate. Results showed that the leaching of PbSO4 in citric acid/sodium citrate solution was remarkably enhanced by an increase in temperature from 35 ◦C to 95 ◦C and...

Germination of Clostridium cylindrosporum Spores on Medium Containing Uric Acid.

Clostridium cylindrosporum spores germinated rapidly under reducing conditions when bicarbonate, uric acid, and calcium were present. Germination rates on 10 mM urate increased with increasing Ca (maximum rate at 5 mM Ca or greater). Germination rates on urate (limiting Ca) increased with increasing urate concentrations to 10 mM urate. At 10 mM Ca, germination rates reached a maximum at 1 mM ur...

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...

Citric Acid Determination

Three types of methods have been proposed for the determination of citric acid in urine. Salant and Wise (1) used the unspecific mercuric sulfate reagent of Deniges (2) in a study of the toxicity of citrates. Thunberg (3) developed an enzymatic method employing a dehydrogenase said to be specific for citrate. The remaining methods depend on the so called pentabromoacetone method of Stahre (4), ...

Citric Acid and Bone Metabolism

From the sedimentation and diffusion constant values obtained in a solution containing 1 g./ 100 ml. H substance, and using the determined value of the partial specific volume, the molecular weight was calculated from the usual equation (Svedberg & Pedersen, 1940) giving a value of 320 000. From the same data the frictional ratio f/fo obtained was 4-2. This corresponds to an axial ratio of > 10...
