Adsorption characteristics of phosphorylated algic acid for lead ions |
| 초록 |
The hydroxyl groups of alginic acid were modified into phosphate groups to increase the uptake capacity of heavy metals. The phosphorylated alginic acid prepared through chemical reaction with mixture of H3PO4 and NaH2PO4 showed a high uptake capacity of about 2.95 mmol Pb/g-dry resin at pH4. Increased number of phosphate groups was confirmed by an alyzing the content of phosphate using molybdophosphoric acid forming. Also, the phosphorylated alginic acid wass uccessfully immobilized by PVA-Boric acid method using glutaraldehyde to reduce the hydration of the immobilized beads.When the phosphorylated alginic acid bead was applied to the process the breakthrough point for lead ions appeared around 700 bed volumes and it shows high selectivity to alkaline metals such as calcium and magnesium ions. |
