abstract: In this research, the magnetite coated salicylic acid was synthesized
through co-precipitation method using ultrasonic wave (Mag-ASUS). This
research was analyzed to gold recovery necessity. The main aim of this research
is to expand the effectiveness of the materials using in adsorption-reduction
[AuCl4]-.
The synthesis was done through co-precipitation method at 60oC using
200 kHz ultrasonic wave, NaOH as precipitating agent, solution Fe3+/Fe2+ with
molar ratio 2:1 and salicylic acid 0.05 M. Mag-ASUS solid synthesized were
characterized using FTIR and XRD. The application of Mag-ASUS to gold
recovery was analyzed by examining the effect of pH, interaction period and
adsorption isotherm.
The research results show that Mag-ASUS not only has good adsorption
capacity, but also has magnetic quality. Hence, the gold recovery was easily done
by external magnetic field. The optimum adsorption of HAuCl4 using 10 mg Mag-
ASUS was achievedat pH 3. The equilibrium was done for 180 minutes. The
adsorption capacity of [AuCl4]- using 2,0x10-4 mol g-1 Mag-ASUS needs 23.6234
kJ mol-1 energy so that it was categorized in chemistry adsorption. This
adsorption was categorized in Langmuir isotherm.
