Method for determination of arsenic in coal by Microwave Digestion-Atomic Fluorescence Spectrometry was established. The influences of instrument parameters on the determination of arsenic were studied. The analytical conditions were optimized. The linear range was 0.4-200 ng/L and the correlation coefficient, 0.9994. The detection limits was 0.12 ng/mL, and the recovery, 94.87%-96.80% and the relative standard deviation, ≤3.20% respectively. The method was simple, rapid, sensitive and can be applied in the determination of arsenic in coal.
