| Abstract: | By using HF solvent to solute pure quartz and dried,using ascorbic acid to reduce in acid medium to Fe~(3+) and Fe~(2+),and form compound of Fe(phen)~(2+)_3 with 1,10 phen.Then adding some ClO~-_4 to form ion compound.By using nitrobenzene to determine and atomic absorption to determine organic phase,limition of detection is 1.1ng/g,and analysis result RSD% is 4.52~10.3. |
| Keywords: | Pure quartz trace iron 1 10 - phen nitrobenzene ectraction-atomic absorption spectrophotometry |
