Determination of soluble bromine in an extra-high-pressure mercury discharge lamp by sodium hydroxide decomposition-suppressed ion chromatography.

چکیده
We have established a simple method for assaying the quantity of soluble bromine in the discharge tubes of an extra-high-pressure mercury discharge lamp. Each discharge tube is destroyed in 5 ml of 10 mM sodium hydroxide, and the recovered sodium hydroxide solution is analyzed by suppressed-ion chromatography using gradient elution. We have clarified that this method can assay less than 1 microg of soluble bromine in a discharge tube.

Rapid determination of mercury species in sewage sludge by high-performance liquid chromatography on-line coupled with cold-vapor atomic-fluorescence spectrometry after ultrasound-assisted extraction.
So far, no research has been focused on the determination of organomercuries in sewage sludge. Here, an ultrasonic extraction method for the rapid determination of methylmercury (MeHg) and ethylmercury (EtHg) in sewage sludge after ultrasound-assisted extraction is proposed. Using TMA (tetramethylammonium hydroxide) as the extractant with 3.0 g copper powder, ultrasonic extraction for 30 min at...

متن کاملDetermination of trace anions in high-nitrate matrices by ion chromatography.
An ion chromatography method was developed to determine trace anionic contamination in matrices that have a high concentration of nitrate ion. Contaminant anions of interest were separated on an IonPac AS15 high-capacity anion-exchange column and detected by suppressed conductivity detection. An EG40 eluent generator was used to prepare high-purity and carbonate-free potassium hydroxide. Using ...
متن کاملA simple method for the determination of iodine in the chick thyroid.
In the routine thyrotropin assay based upon the depletion of iodine in the chick thyroid gland following thyrotropin injections, a rapid micromethod for the determination of iodine was desirable. Elmer (1) gives an excellent critical review of the existing methods for iodine determination up to 1936. Kirk (2) reviews the present methods and techniques for microanalysis, including iodine. The me...
