| titleOfInvention | A kind of measure the method for plumbum ion concentration in PM2.5 |
| abstract | The present invention relates to a kind of measure the method for plumbum ion concentration in PM2.5, first drip decorating liquid to glassy carbon electrode surface and toast, glass-carbon electrode is inserted in the glycine mixed solution with sodium nitrate as working electrode and auxiliary electrode and reference electrode jointly, it is repeatedly scanned with and makes glassy carbon electrode surface be coated with polyglycine multi-walled carbon nano-tubes/naphthols/epoxy phosphate membrane of lipoprotein, then modified electrode is inserted in the end liquid containing lead ion as working electrode, electrochemical workstation provides volt-ampere curve summary view, the current peak that each plumbum ion concentration occurs is read from summary view, then plumbum ion concentration and current peak graph of a relation are drawn, draw linear relationship formula between the two, the circular filter paper of PM2.5 sample is lighted after incinerating, at HNO 3 Dissolving in end liquid, insert in the end to be measured liquid using above-mentioned modified electrode as working electrode, electrochemical workstation provides volt-ampere curve figure, reads the current peak that lead ion occurs, calculates plumbum ion concentration by formula.The method is fast and convenient accurately. |
