“…A novel but indirect method for the determination of I by AFS was reported by Lu et al 71 Marine samples were acid digested then mixed with aqueous Hg 2+ with the resultant H 2 HgI 4 species extracted with IBMK. Aer phase separation, KBH 4 was added to generate Hg vapour which was analysed by AFS.…”

“…7.1.4 Other elements. Indirect assay of the halogens is one possible approach for measurement by non-MS techniques and a method for the determination of I at low levels was proposed by Lu et al 71 A stable complex, H 2 HgI 4 , formed with the Hg 2+ in an acidic medium (HNO 3 ) and was extracted into IBMK in which it remained for the reduction step, with KBH 4 . A precision of 2.15% RSD was achieved with an LOD of 0.038 mg L À1 and a linear range between 0.04 and 20 mg L À1 .…”
