| Abstract |
Presentation of a modified photometric method in which paper filters are replaced by ash-free filters. This enables air sampling speed to be considerably increased (50-100l/min; previously 5l/min), and to limit sampling time to 20min. Furthermore, arsenic extraction takes only 35-40 min, compared to 5-6h previously. Pyridine in the absorption solution is replaced by a solution of 1% ethanolamine in chloroform. These modifications do not affect determination limits because relative error is 19.6% for 2µg As in the sample (5.8% for 10µg). Sensitivity of the method is around 0.003mg/m3. |
