| Abstract: | Coexistence elements including Mn, Cr, Ni, Cu, Co and Zn seriously interfere with determining trace Cd in environment waste water by graphite furnace atomic absorption spectrophotometry. Using 100mg/L of Fe as matrix modifier can eliminate the interference of the coexistence elements above and the result is satisfied. |
