Monopotassium monosodium tartrate tetrahydrate Use and Manufacturing
It is obtained by neutralizing tartaric acid with potassium hydroxide and sodium hydroxide. In the reaction pot equipped with stirring and steam heating tube, add solid alkali, liquid potassium hydroxide, add water to dissolve. Tartaric acid was added with heating and stirring until the pH of the solution was 7. Suction and filtering while hot, put the filtrate into the crystallization pot, cool and crystallize. After suction filtration, wash with water to remove chlorides, boil and dry below 48 ℃ to be the finished product.

NIOSH Method: 173. Analyte: Sodium. Matrix: Air. Procedure: Atomic absorption spectrophotometry. This method has a detection limit of 0.0002 and sensitivity of 0.015 ug/ml. The working range for a precision better than 3% RSD/CV is 0.05-1.0 ug/ml. Interference: Spectral, ionization, chemical and physical interferences. /Sodium/|NIOSH Method: 7300. Analyte: Sodium. Matrix: Air. Procedure: Inductively coupled argon plasma, atomic emission spectroscopy. For sodium this method has an estimated detection limit of 10 ng/ml sample. The precision/RSD and the recovery are not determined. Applicability: The working range of this method is 0.005 to 2.0 mg/cu m for each element in a 500 liter air sample. Interferences: Spectral interferences. /Sodium/|NIOSH Method 173. Analyte: Potassium. Matrix: Air. Procedure: Atomic absorption spectrophotometry. This method has a detection limit of 0.002 ug/ml and sensitivity of 0.04 ug/ml. The working range for a precision better than 3% RSD/CV is 0.1-2.0 ug/ml. Interferences: Spectral, ionization, chemical, physical interferences. /Potassium/|Method 3500-Potassium C. Inductively Coupled Plasma Method for the determination of potassium in water and wastewater. Trace amounts of potassium can be determined in either a direct-reading or internal-standard type of flame photometer at a wavelength of 766.5 nm. Magnesium begins to interfere when the magnesium-to-potassium ratio exceeds 100:1. Minimum detectable concentration: Potassium levels of approximately 0.1 mg/l can be determined. A synthetic sample containing 3.1 mg potassium/l was analyzed in 33 laboratories by the flame photometric method, with a relative standard deviation of 15.5% and a relative error of 2.3%. /Potassium/|For more Analytic Laboratory Methods (Complete) data for SODIUM POTASSIUM TARTRATE (9 total), please visit the HSDB record page.
