Ion-Exchange Fibres for the Recovery of Gold Cyanide

Polyacrylamide thorium (IV) phosphate as an important lead selective fibrous ion exchanger: Synthesis, characterization and removal study

“…To know the minimum volume required for complete elution, an experiment was conducted by passing 1 M sodium nitrate solution in different 10 mL portion with a flow rate of 0.5 mL/min in a similar column containing 1 g of the ion exchanger. To study the thermal stability, 1 g samples of polyacrylamide thorium (IV) phosphate were heated at different temperature in a muffle furnace for 1 h and their ion 2 3.01 Pb(NO 3 ) 2 3.89 exchange capacities were determined by usual column process after cooling them to the room temperature. The result obtained is represented in Table 3.…”

“…This difficulty is eliminated when fibrous ion exchange materials are used since the layer resistance is easily predetermined by the density of a fibrous material packing in accordance with technological requirements. Because of the above reason, these materials are of great importance and will gain momentum in future [2,3].…”
