Copper of high purity. Method of chemical-atomic-emission analysis
Медь высокой чистоты. Метод химико-атомно-эмиссионного анализа
Status: Not effective - Superseded. Information about the registration of 51st from 02/17/2016 (the official website of Rosstandart); see IUS 7-2016
This standard establishes a chemical-atomic emission method for measuring the mass fractions of impurities in copper.
Настоящий стандарт устанавливает химико-атомно-эмиссионный метод определения примесей в меди высокой чистоты в диапазоне массовых долей х.10 в степени минус 4 %. Метод заключается в растворении навески меди в смеси соляной кислоты и перекиси водорода, отделении меди от примесей экстракцией ди-2-этилгексилдитиофосфорной кислотой, получение концентрата примесей на графитовом порошке с носителем - хлористым натрием и анализе концентрата атомно-эмиссионным методом в дуге постоянного тока с фотографической регистрацией спектра
