1. N, N-Dimethylpiperidinium iodide is recommended as a reage palladous ions. In neutral or acidic solution, it forms a black or brown precipitate with palladous ions deperding on the amount of the latter present.The sensitivity is 0.2 r (1:200,000) on the spot plate and 0.006 r(1:200,000) on the filter paper.
