Abstract
In this research, in-situ polymerization is used to prepare composite material at the same ratio of (polyacrylic acid to bentonite) and (10ml) aquaregia (1:3 HNO3: HCl), accurately about (5g) of the electronic waste (e-waste) powder is dissolved. Adsorption efficiency of (Polyacrylic acid - bentonite) composite to precious metals from neutral (e-waste) solution via forth flotation method, taking various weights (2.5, 5, 10 g.l−1) of adsorbent material (polyacrylic acid - bentonite) composite at different temperatures (25, 35 and 45) °C. Results show that adsorption efficiency of Au+1 is higher than Ag+1 from adsorbent material and the highest value is (53.238%, 43.3904%), (51.778%, 41.99%) and (51.278%, 39.595%) for (Au+1, Ag+1) at (25, 35 and 45)°C respectively. But it is decreased slightly with increasing temperature.
