[ 1 ] - Determination of trace amounts of chromium ions in water and food samples using ligand-less solid phase extraction-based modified nano-boehmite(AlOOH)

Chromium is one of the hazardous pollutants in industrial effluents. In this study, a new nano-boehmite modified with sodium dodecyl sulphate is developed for preconcentration trace amounts of chromium ions as a prior step to its determination by flame atomic absorption spectrometry. We investigated the effect of various parameters on the recovery of the analyte ions, including pH of sample solut...
