This research demonstrates effective analysis of chloride ions in solution using GPTMS-modified silica gel, suggesting its potential in ion chromatography.
Key Points
GPTMS-dimethylamine modified silica gel effectively analyzes chloride ions in ion chromatography.
Quantitative method employed with chloride concentrations set at 100 ppm, 200 ppm, and 300 ppm.
The optimal chromatogram peaks were produced using 0.1 M Na₂CO₃, indicated by high linearity (R² = 0.9733).
This study highlights the potential use of modified silica gel as an ion-exchange resin for chemical analysis.
