Abstract
Determination of mercury and arsenic in surface water with potassium borohydride as reducer by atomic fluorescence spectrophotometer with gas driven injection was simple, less reagent using and sensitive In detection of mercury, concentration of KBH 4 KOH was 0 01%～0 0005%, concentration of aqua regia in sample was 3%(v/v), detection limit was 5 8×10 -3 μg/L In detection of arsenic, concentration of KBH 4 KOH was 2 6%～1 0%, concentration of HCl in sample was 5%(v/v), detection limit was 4 9μg/L
