A Facile Synthesized Polyaniline Coated Zerovalent Iron-Silica as an Efficient Sorbent for

A synthesized Fe@SiO2@PANI sorbent achieved a wide linear dynamic range of 0.012-10.000 μg mL-1 and a reusability of up to 16 cycles. The method, developed by Jirasak Gamonchuang, demonstrated limits of detection between 0.001-0.030 μg mL-1 and recoveries of 83.4-118.9% in environmental water samples. Parameters like sorbent amount, extraction time, and pH were optimized for magnetic solid-phase extraction prior to HPLC-PDA analysis.

Use Cases

• Optimizing magnetic solid-phase extraction protocols based on described parameters like sorbent amount and pH.
• Benchmarking new sorbent materials against reported performance metrics like linear range and detection limits.
• Modeling adsorption affinity and reusability for phenolic pollutants based on the 16-cycle test results.
• Validating HPLC-PDA analysis methods for environmental water samples using the reported recovery ranges.

Strengths

• Reported a wide linear dynamic range of 0.012-10.000 μg mL-1 with coefficients of determination better than 0.9926.
• Demonstrated good sorbent reusability, maintaining performance for up to 16 extraction cycles.
• Achieved method precision with relative standard deviation (RSD) better than 11%.
