Determination of group parameters for organically bound chlorine, bromine and iodine in precipitation

Iodine speciation in rain and snow: Implications for the atmospheric iodine sink

“…Murphy et al [1997] and Middlebrook et al [1998] have also elegantly shown, using the PALMS instrument, a strong association between iodine and organic rich particles in unpolluted aerosols of marine origin. In contrast, Laniewski et al [1999] found very little iodine associated with organics in rain and snow. However, this is more likely a function of the AOX method used to isolate the organo-halogens as it was initially developed for wastewater rather than trace analytics.…”

A review on iodine speciation for environmental, biological and nutrition fields

“…196 Other applications include the use of S-X3 Biobeads gel permeation for retaining inorganic iodine from organic extracts containing extractable organoiodine compounds from blubber (Weddell seal samples) before NAA; 197 or activated carbon for retaining adsorbable organic iodine (AOI) from rainwater. 198 SPE using pre-packed standard stainless steel cardridges with Tenax TA and Carbograph 1TD can be used for retaining polyfluorinated iodine alkanes from air samples followed by thermal desoprtion GC-MS. 24 Also for iodine species in air samples (iodine, iodine monochloride and hypoiodous acid) and GC-MS determinations, iodinated species can be retained in different denuder systems coated with N,N-dimethylaniline HPLC-UV (RPC): as described above Ref.…”

Chloride retention in forest soil by microbial uptake and by natural chlorination of organic matter

“…Tests confirmed that leading the gas stream through two scintillation vials in series, each holding 10 ml 0.1 M NaOH, yielded a recovery of >98% of the 36 Cl added to the soil prior to combustion. This technique to recover Cl after combustion was previously described by Laniewski et al (1999). The filtrate was used without further treatment for LSC yielding 36 Cl in (Fig.…”
