Applications of Chromatography in the Analysis of Inorganic Materials
The role of separations in inorganic analysis is discussed and the advantages of various chromatographic techniques are stressed. Major separation methods include solvent extraction, column extraction chromatography, gas chromatography of volatile metal chelates, ionexchange chromatography, and column chromatography employing chelating resins and non-ionic sorptive resins. The use of each of th...
متن کاملAdvances in the determination of inorganic anions by ion chromatography.
The time period covered for this review includes articles published from 1997 to 1999, with the addition of a few classic references. The purpose of the review is to include the most relevant works from each topic area of the determination of inorganic anions by ion chromatography, including new sample pretreatments, new separation methods, new detection systems and the latest applications in t...
متن کاملFast ion chromatography of inorganic anions and cations on a lysine bonded porous silica monolith.
A 0.46 cm x 10.0 cm silica monolith column was modified through the in situ covalent attachment of lysine (2,6-diaminohexanoic acid) groups. Due to the zwitterionic nature of the resultant stationary phase, the modified monolithic column contained both cation and anion exchange capacity. In the case of cation exchange, the capacity was found to be relatively low at between 5 and 6.5 micromoles ...
متن کاملDetermination of inorganic anions in natural water by microcolumn ion chromatography with on-column enrichment.
An on-column enrichment method was developed for the rapid determination of inorganic anions in natural water. The system was assembled from a syringe pump, a six-port switching valve with a sample-enrichment loop, a separation column and a UV detector. The enrichment efficiency of the system was tested by using inorganic anions as samples. The limits of detection were between 0.6 and 7.7 micro...
متن کاملDetermination of total dissolved inorganic carbon in freshwaters by reagent-free ion chromatography.
Studies of inorganic carbon cycle in natural waters provide important information on the biological productivity and buffer capacity. Determination of total inorganic carbon, alkalinity and dissolved carbon dioxide gives an indication of the balance between photosynthesis and respiration by biota, both within the water column and sediments, and carbon dioxide transfers from the water column to ...
