High purity lead iodide (PbI 2 ) is prepared by precipitation of lead nitrate (Pb(NO 3 )) and potassium iodide (KI) solutions. Thoroughly dried PbI 2 is then zone refined. The main impurity causing a strong adherence of solidified melt to the glass ampoule wall is identified to be lead...

Precipitation and indirect spectrophotometric determination of sulfate traces in fresh water with lead nitrate and tetraphenylporphine trisulfonic acid 来自 Springer 喜欢 0 阅读量: 13 作者:T.,Honjo,N.,Hayashi 摘要: We describe a rapid procedure using propidium iodide (PI) as a nuclear counterstain ...
Lead does not evolve hydrogen readily with acids. Nitric acid attacks the metal readily, forming lead nitrate and oxides of nitrogen: 3Pb + 8HNO3 → 3Pb(NO3)2 + 2NO + 4H2O This reaction is faster in dilute nitric acid than strong acid. Hydrochloric acid has little effect on the metal...
