Development of surfactant assisted spectrophotometric method for determination of selenium in waste water samples

Assessment of trace metal levels in some moss and lichen samples collected from near the motorway in Turkey

“…Trace metal analyses in environmental samples including natural waters, foods, mushrooms, lichens and moses by the spectroscopic methods are very important for human health [26][27][28][29][30][31][32][33][34][35][36]. The microwave digestion procedure was chosen for the samples because of more accurate with respect to both time and recovery than wet digestion.…”

Bentonite modification with hexadecylpyridinium and aluminum polyoxy cations and its effectiveness in Se(IV) removal

“…It is enriched generally in phosphate deposits, metal sulfur deposits, coal mines, volcanic soils, coal fly ash basins and epithermal deposits (Bryan et al, 2012;Floor and Rom an-Ross, 2012;Bech et al, 2010). Its concentration increases in aqueous environments due to natural processes, such as weathering of rocks, erosion of soils, water seepage from selenium enriched ore deposits or due to anthropogenic activities such as mining activities, fossil fuel processing, combustion, industrial, agricultural and metallurgical processes (Agrawal et al, 2009). It can be toxic depending on its concentration in the environment.…”

Selective determination of selenium(IV) from environmental samples by UV-visible spectrophotometry usingO-methoxyphenyl thiourea as a chelating ligand

“…A large number of methods are reported for the determination of selenium(IV). The comparison of the present method with reported methods for spectrophotometric determination of selenium(IV) is presented in Table 1 [18,[20][21][22][23][24][25][26].…”
