Precisely weighed, slowly ignited to complete carbonization, let cool; unless otherwise specified, add 0.5~1ml of sulfuric acid to make it moist, low temperature heating until the sulfuric acid vapor is removed, and then completely ash at 700~800 degrees. Displace the dryer, let it cool, accurately weighed, and then burn to constant weight at 700~800 degrees.
