The choice of extraction conditions - - In analytical chemistry
month, vico technology announcement said, vico technology co. , LTD. , co. , LG chemical and nanchang new district days investment co. , LTD in year month day to sino-foreign joint venture contract, proposed joint venture management and setting up Jiang Xiwei battery co. , LTD. , the project total investment for the thousands of dollars, registered capital of million dollars. Vico technology, LG chem and days together investment contribution respectively. Million dollar,. Million dollar,. Dollars, respectively, holding %, %, % equity joint venture. The joint venture term of years from the date of establishment. Extraction conditions for the choice of the selection of extraction agent a stable chelate, strong hydrophobicity, high extraction rate. B solution acidity ph affects the dissociation of extractant, the stability of the complex, the hydrolysis of metal ions. C the selection of extraction solvent low metal complex have larger solubility in the solvent, as far as possible by structure and complex structure similar to that of solvent, low solvent extraction of aqueous solution density and the density of the difference is bigger, smaller viscosity, easy layering, small, low toxicity, non-toxic, best and less volatile. Above is the medical education website small make up for 'options - extraction conditions - The content of the analytical chemistry 'finishing, hope everyone in the process of preparing to review carefully. For more information please pay close attention to medical education network.
