| titleOfInvention | Titrimetric method for quantitative determination of the zinc content of non-ferrous concentrates |
| abstract | The invention relates to a titrimetric method ofnquantitative determination of the zinc content ofnnon-ferrous concentrates, used for quality controlnores, having a higher zinc contentnof 5%, consisting of the oxidative acid disintegrationnwith freshly prepared royal water, with heating tondry and adding dropwise nitric acid,nseparation of lead by precipitation with sulfuric acid,nseparation of interfering elements, manganese andnoxidized iron, by precipitation with excess ammonia,nat pH = 10, Cu2 + ions being reduced to Cu ions *nwith a solution of 30% sodium thiosulphate and a solution ofnSodium fluoride 2% at pH = 6 and titration with onenEDTA solution, with xylene orange as indicator, innbuffer solutions, at pH = 5.7. |
