## Abstract A sensitive and selective method for the determination of Pb(II) with a zirconium phosphated silica gel (SiZrPH) modified carbon paste electrode has been developed. The measurements were carried out in three steps including an open circuit accumulation following by electrolysis of accum
The rotating rmgcIisc electrode technique was used to study the generation of soluble Pb(II) species during the anodic oxidation of the lead electrode in various HIO-H,SO, media. The concentration range cxtcnded from 0.06 to 10.3 M H,SO,. For every concentration it was possible to detect a small cat
