And yes, a handheld XRF still costs 35k So why bother to prepare samples for the microscope when a simple test shows that there is no nickel anyway? , Field methods for the determination of nickel using dimethylglyoxime Economic Geology 57 (1962) 595-604 , Feigl, F: Spot tests in inorganic analysis Elsevier, 1958 Schuster, N .
Dimethylglyoxime | Article about Dimethylglyoxime by The ,
With nickel salts it yields a red insoluble precipitate of nickel dimethylglyoximate, (C 4 H 7 O 2 N) 2 Ni, which is a chelate compound Because of this, dimethylglyoxime is used for the qualitative and quantitative determination of nickel
Gravimetric Determination of Nickel using Dimethylglyoxime
To obtain a gravimetric determination of nickel using dimethylglyoxime: Weigh and measure a sample so that not over 100 mg Of nickel present Add 10 cc’s of nitric acid 5 to 1 grams of potassium chlorate and digest on the steam plate adding more potassium chlorate if necessary to effect solution Evaporate to dryness Cool slightly and add 5 cc’s of HCl
