Fruit and vegetable crop multielement organic liquid fertilizer and producing method thereof

Abstract: The invention provides a fruit and vegetable crop multielement organic liquid fertilizer which comprises the following components by mass: 17%-23% of potassium humate; 30%-36% of organic matters, 20% of potassium dihydrogen phosphate, 19%-25% of potassium nitrate, 2%-7% of calcium ammonium nitrate, 1%-2% of magnesium sulfate, 0.5%-1.2% of ferrous sulfate, 0.5%-1.2% of borax, 0.5%-1.2% of zinc sulfate, 0.4%-0.7% of copper sulfate, 0.01%-0.5% of a conditioner and 0.01%-0.3% of molybdate ammonium. The fruit and vegetable crop multielement organic liquid fertilizer solves the problems of incomplete multielements required by the plant, low plant absorption rate, unobvious use effect and high fertilization cost caused by single nature of the fertilizer varieties in the prior art.

Nonaqueous purification of mixed nitrate heat transfer media

Abstract: A nonaqueous, in-line method for removing carbonate and hydroxide contamination from a molten mixed sodium nitrate/potassium nitrate heat transfer salt. The method comprises dissolving a stoichiometric quantity of anhydrous Ca(NO3)2 in the melt whereby an insoluble CaCO3 and Ca(OH)2 precipitate is formed. The precipitate can be removed by settling, filtration or floatation techniques.
