Determination Of Copper

Abstract A titrimetric and an electro-deposition method for copper naphthenate were studied collaboratively. The titrimetric method involves shaking the sample with KI and ammonium bifluoride in aqueous solution and titrating the liberated iodine with standard thiosulfate solution. The electro-deposition method involves extracting the sample with (1 + 4) HNO3 and petroleum ether, and electrolyzing the solution at 2 amps. The titrimetric method is accurate and reproducible; the electro-deposition method showed over-all negative bias.

Determination Of Copper

AbstractA simple photometric method for copper (II) analysis using monosodium glutamate (MSG) is presented. The method is technically simple, inexpensive, quantitative, and makes use of readily available reagents. The rapid reaction of copper (II) with glutamate in aqueous solution at pH 10 to form a blue complex serves as a basis for the determination of copper (II) in the range of 10-500 μg/ml. Copper recovery is > 82%. The method could be used to determine copper (II) concentrations in iron ore samples.
