An arsenic chemical speciation study was performed in 2000, using air filters on which total suspended particles (TSP) were collected, from the city of Huelva, a medium size city with huge industrial influence in SW Spain. Different procedures for extraction of the arsenic species were performed using water, NH2OH.HCl, and H3PO4 solutions, with either microwave or ultrasonic radiation. The best optimised extraction methods were use of 100 mmol L(-1) NH2OH.HCl and 10 mmol L(-1) H3PO4 and… CONTINUE READING
