Extraction of Mesoporous Silica from Local Soil Samples and Using as Sorbent in Dispersive Solid Phase Extraction Application
Year: 2025
Type: article
Abstract: Mesoporous silica was successfully extracted from selected local soil samples (sandy, clay, and loamy) from Karbala city using sol-gel method. The extraction method was simple and environmentally friendly. Pure silica was characterized using different techniques such as EDX, SEM, BET, XRD, and FTIR. Amorphous silica was used as an adsorbent to extract Fe(III)-salicylicaldehyde oxime complex from aqueous solutions using solid phase extraction method. The optimum conditions of method were 0.10 gm of silica, 0.04 mol.L-1 of salicylaldehyde oxime reagent, pH 7.0 , temperature 35°C, shaking time 15 min, which showed very good extraction percent of Fe(III) - salicyaldehyde oxime complex 99.5%. This indicates the success and selectivity of this method and its application to pharmaceutical samples containing iron (III) ions.It was concluded from this method that it is an easy ,fast, low cost and high sensitively method.
