Microwave Digestion-Lead Molybdate Gravimetric Method for Determining Molybdenum Content in Roasted Molybdenum Concentrate
Microwave digestion method is used to digest roasted molybdenum concentrate samples.Molybdate ions in lead acetate precipitation solution are used to generate lead molybdate precipitate,which is filtered,washed,burned,and weighed.The molybdenum in the residue after ammonia separation is determined by thiocyanate spec-trophotometry and corrected to obtain the molybdenum conten.The measurement range is 40.00%to 65.00%,and the relative standard deviation(RSD)is less than 5%.
