Table 4
Applications: extraction of phosphate ions from samples collected from polluted waters using method developed in this work.
| S. number | Samples collected at different places | (mg/L) (concentration of phosphate in the sample)
| (mg/L) (concentration of phosphate remaining after removal) | % of maximum extraction of phosphate |
| 1 | Sample 1 | 21.5 | 0.5 | 97.6 | 2 | Sample 2 | 25.5 | 1.5 | 94.1 | 3 | Sample 3 | 29.5 | 2.7 | 90.8 |
