摘要: In order to identify the most suitable method for estimation of nanosulfur studying its residue dynamics, present work was taken up. HPLC and GC methods were explored analysis. A comparative study existing analytical quality control undertaken. UV spectrophotometry superior with lower LOD when compared GC-MS, which not satisfactory due breakage catenated S20 into S6 S8 . The has been validated by analyzing various formulations known concentrations. recovery ranged from 80.71 109.51% 82.31 109.84%, respectively. UV, is 4, 20, 1 ppm, retention time sulfur 13.77 (HPLC), 2.89 (ultra high performance liquid chromatography), 12.715 + 21.524 min (GC-MS). successfully utilized estimating in natural samples such as water a hot spring wastewater. following recommended American Society Testing Materials. emerged best elemental sulfur.
