Cr(III) slowly forms a violet complex with EDTA at pH 2.5-5.0 under normal conditions. The complex formation can be accelerated by irradiating the reacting mixture with microwave energy. The complex Cr(III)-EDTA is completely formed within 3 minutes of microwave irradiation and followed by a simple and rapid method for spectrophotometric determination of chromium. The method may be successfully applied to determination of chromium in catalyst.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-12-19T14:50:27Z No. of bitstreams: 1 v22_n2_%20(8).pdf: 203641 bytes, checksum: abcf4e328e1f6bb7afe12af3c69bc79a (MD5)Made available in DSpace on 2011-12-19T14:50:27Z (GMT).
