The reaction is preferably carried out in the presence of an inert porous carrier which is solid at the temperature employed, e.g. CaCO 3 . The calcium nitrate is either sprayed as a solution on to the carrier which is at a temperature between 500 and 600 C. or is mixed with a ...

decomposition of carcinogenic substances in sub ammonium nitrate; accelerate the dissolution of bladder stones, kidney stones; help the body to eliminate excess cholesterol, can prevent arteriosclerosis, treatment, lower blood pressure, increase the ability of regeneration of liver a 正在翻译,请等待......
Due to the high solubility of calcium nitrate, the concentration of TN in the overlying water of group G remained at a high level within 0–10 days. During the initial stage (0–10 or 17 days), the TN concentration in the overlying water of D, L and T groups exhibited a significant ...
power, the wetting time, the resistance to acid hydrolysis, and the calcium-ion stability of this series of surfactants were examined, and the results were compared with those of the corresponding sodium alkyl beta-sulfopropionates ROCO(CH2)(2)SO3Na, which have another structure of ester-...
They are responsible for nitrogen fixation in the soil. They change nitrogen into a simpler form such as ammonia, nitrate, and nitrite that can be used by other organisms or plants in the food chain. Detritivores and Scavenger Detritivores ...
It is a type of decomposition in which a single reactant is broken down into more than one product with the help of heat. Thermal energy or heat energy is used to break the reactants. This is an endothermic reaction as heat is used to break the bonds of the reactants. Calcium carbon...
In this work, the metallic layers were prepared by dipping the aerogel into nickel nitrate hexahydrate (Ni(NO3)2·6H2O) and copper nitrate hemi(pentahydrate) (Cu(NO3)2·2.5H2O) solutions. After the removal from the solution, the treated materials were kept overnight at ambient conditions ...

We used a subset of the global change manipula- tions: two levels of precipitation (ambient and ~ 40% reduction) and two levels of nitrogen (ambient or 60 kg N ha − 1 year − 1 added as slow-release calcium nitrate) applied to subplots within precipitation treatments (Allison et al...
