The key to this method is the production of chlorine radicals when aqueous solution saturated with CCl4 is exposed to ultrasonic waves of 40 kHz. The effects of sonication period, CCl4 solution volume, acidity, and interferences were discussed. The time required for a single determination is lower than 2 min. The relative standard deviation obtained for aqueous solutions with 1 µg of Cr was <2% (N = 10) and the calculated detection limit (3σ) was 5 ng of Cr.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2012-12-10T20:28:06Z No. of bitstreams: 1 _pdf.pdf: 60971 bytes, checksum: c549e5680b649ab3e9b67f8ebf886841 (MD5)Made available in DSpace on 2012-12-10T20:28:06Z (GMT).
