The invention relates a process for producing an alkali metal nitrate and an alkali metal phosphate in the same process from a phosphate raw material and a nitrate raw material comprising the steps of: a) reacting the phosphate raw material with the nitrate raw material to provide an aqueous nitrophosphate feed, optionally followed by the separation of solid material, b) introducing the

Development of efficient sorbents by alkali-treatment of

2016-6-24 · The high calcium content of fly ash had an unfavorable impact on the ammonium removal capacity of zeolite [9, 10]. However, effective phosphate removal by high-calcium fly ash-based zeolites has been observed [10– 12]. In some cases, high-calcium fly ashes required the addition of silica or alumina in order zeolite synthesis to for occur [3, 13].

Ethylenediaminetetraacetic acid | C10H16N2O8 - …

Edetic Acid is the acid form of edetate, a chelating agent with anti-hypercalcemic and anticoagulant properties. Edetic acid binds calcium and heavy metal ions, forming soluble stable complexes which are readily excreted by the kidneys. This results in a decrease in serum calcium levels. This agent is also used as an anticoagulant for blood specimens and is applied as a treatment of lead
