چکیده
In present study, a solvent extraction experiment has been done to separate cobalt from the nickel sulfate solution by using 2-ethythexyl phosponic acid mono-2-ethylhexyl ester (PC-88A) as extractant. The was carried out on laboratory scale separating funnel extract with PC88A. mixed shake in for specified period of time, and after finished organic phase PC88 separated decantation. content aqueous were then analyzed Atomic absorption spectrophotometry (AAS). this experiment, variable experiments covering pH 2 6, shaking time 30 minutes 120 minutes, speed 20 revolutions per minute (rpm) 80 rpm, volumeratio (A:O ratio) 1:1 1:4. effects that experimental variables observed experiment. result at room temperature, 5, 60 90 A:O ratio 1:4 concentration PC- 88A 40% show 97.21% can be extracted PC-88A solution, thererfore it necessary conduct two stage process 100% solution.
