I synthesized SmCo5 (Samarium Cobalt) samples in which I found many impurities of Cobalt Oxide (CoO). Can anyone suggest me how to dissolve CoO without affecting my SmCo5 formation?. I tried with
1. dilute acetic acid,
2. dilute Hcl
3. few drop of H2O2
None worked out. CoO was completely found. Kindly suggest me with the right one.
Hello,
I think that needed to conc. acid, use HCl alone or conc, HNO3 alone or mixture if not dissolved........

Shereen Saju Dear Shereen, have you solved the dissolution of CoO? I also face the problem, coud you give me some suggestion. Thanks.
