Competitive sorption and desorption of cadmium and …

25/7/2012· Sorption isotherms were well fitted with one-metal and competitive Langmuir equation for single- and binary-metal system, respectively. The distribution coefficient ( K d ) values were K d single (Pb) > K d binary (Pb) > K d single (Cd) > K d binary (Cd), indiing that Pb was stronger sorbed by these soils than Cd in binary metal system.

Dietary reference values for sodium - - 2019 - EFSA …

Calcium and sodium share common transport mechanisms in the kidney; the reabsorption of calcium parallels the reabsorption of sodium at the renal tubular level (Yu, 2015; Moor and Bonny, 2016). There is consistent evidence that an increase in sodium intake increases urinary calcium excretion, while a reduction in sodium intake lowers urinary calcium excretion (Afssa, 2001 ; EFSA, 2005a ; IOM

Re‐evaluation of sodium ferrocyanide (E 535), potassium …

Calcium ferrocyanide is produced by reacting sodium ferrocyanide with calcium hydroxide, as visible above. According to Stolzenberg ( 2005 ), Na4[Fe(CN) 6 ]·10H 2 O is produced from calcium cyanide, iron(II) sulphate, and sodium carbonate in aqueous medium at 100°C, with a process similar to that described hereafter for the potassium derivative.
