Used for trace analysis of potassium, sodium, etc. The basic principle of atomic absorption spectroscopy (AAS) is to measure the absorption of resonant radiation by ground-state atoms. Potassium and sodium are easily ionized in a high temperature flame, thus reducing the number of ground-state atoms involved in atomic absorption. It is more obvious especially in the low concentration of potassium. Generally the concentration of sodium in the water is higher than potassium, that is a large amount of sodium to potassium intensifying action. Adding cesium which is more easily ionized than potassium and sodium as ionization buffer, to provide enough electronic to keep the ionization balance moving to the direction of generating the ground state atoms, then can be continuously measured in the same copy of sample of potassium and sodium.
Preparation of other cesium salts. Detection of radioactive substances in environmental control analysis. Oxidant.
Functions and Applications
Cesium nitrate (or other compounds with nitrate, such as copper nitrate and magnesium nitrate) can be reacted with nitric acid to generate cesium nitrate, must meet the conditions of the double decomposition reaction, such as copper nitrate and magnesium nitrate). The reaction equation is as follows:
Reaction with nitric acid: CsOH+HNO3==CsNO3+H2O
Reaction with copper nitrate: 2CsOH+Cu(NO3)2==Cu(OH)2↓+2CsNO3 (Copper hydroxide is a by-product of the reaction, and cesium nitrate solution is filtered)
Reaction with magnesium nitrate: 2CsOH+Mg(NO3)2==Mg(OH)2↓+2CsNO3 (operation as above)
Note: during above reactions, using Cesium hydroxide as raw material is relatively dangerous to be prepared with water. Using Cesium and water can generate directly. The reaction equation is as follows:
Cs + 2 h2o csoh + H2 = = 2 write
