A method is described for the determination by atomic-absorption spectrophotometry of molybdenum in flotation tailings by using dichloromethane as solvent which is less poisonous than the commonly used chloroform. Little difference was observed between dichloromethane and chloroform in the determination of a standard molybdenum solution. It was found that dichloromethane was also an effective solvent for the determination of a very small amount of molybdenum in flotation tailings by Hutchison's procedure. The accuracy obtained by dichloromethane was comparable to that observed for chloroform; the variation coefficient being 2.3 % for dichloromethane compared with 1.5 % for chloroform.
