  "abstract": "Conventional colorimetric Hg²⁺ sensors primarily target trace-level detection, limiting their applicability to industrial wastewater containing elevated mercury concentrations. Herein, a silica-supported APTES-TEOS ion-imprinted polymer (SiO₂@MIP) was developed for smartphone-assisted colorimetric detection of high-load Hg²⁺ in industrial wastewater. The synthesized material was characterized using FTIR, Raman spectroscopy, and XPS, while Hg²⁺ detection was evaluated using UV-vis spectrophotometry and the Photometrix smartphone application. The proposed method exhibited a working concentration range of 1 mM-100 mM, with adsorption saturation observed above approximately 12.5 mM and a strong logarithmic calibration relationship (R ² = 0.9878), a limit of quantification was calculated to be 1.35 mM. Selectivity experiments demonstrated preferential Hg²⁺ recognition in the presence of competing metal ions at 10 mM and in mixed-ion matrices. The method exhibited satisfactory reproducibility, with RSD values ranging from 2.9% to 5.9% within the investigated quantification range. Spike recovery experiments in industrial paper-manufacturing wastewater yielded recoveries of 94.02-96.11%, comparable to those obtained using ICP-MS as a reference method (95.24-99.84%). These results demonstrate the potential of SiO₂@MIP-based smartphone colorimetry for practical screening of high-load Hg²⁺ in industrial wastewater without requiring sophisticated analytical instrumentation during routine measurements.",
