Polypyrrole-magnetite dispersive micro-solid phase extraction for the determination of rhodamine 6G and crystal violet in textile wastewater

Polypyrrole-magnetite (PPy-Fe3O4) dispersive micro-solid phase extraction (PPy-Fe3O4-D-μ-SPE) method combined with ultraviolet-visible (UV-Vis) spectrophotometry was developed for the determination of the selected basic dyes in textile wastewater. PPy-Fe3O4 was used as adsorbent due to its stability...

Under the optimized conditions, PPy-Fe3O4-D-μ-SPE method showed good linearity in the range of 0.05-7 mg/L with coefficient of determination R2 > 0.998. The method showed good limit of detection (LOD) for the basic dyes (0.05 mg/L) and good analyte recoveries (97.4 to 111.3%) with relative standard deviations (RSD) < 10%.
