PENGARUH Co(II) PADA TRANSPOR Ni(II) MELALUI TEKNIK MEMBRAN CAIR FASA RUAH DENGAN DIMETILGLIOKSIM SEBAGAI ZAT PEMBAWA
Abstract: The influence of
Co(II) on Ni(II) transported by dimethylglyoxime as carrier through bulk liquid
membrane has been investigated. The
Concentration of Ni(II) and Co(II)
that has transported to receiving
phase and remaining
in donor phase
were determined by
atomic absorption spectrophotometry at
λmax 232 nm and λmax
240,7 nm. The
optimum conditions for
transport process of Ni(II) was used at pH 4 in donor phase,
dimethylglyoxime concentration was 6.8 x 10-4 M in membrane phase, 0.05 M
Na2EDTA concentration at pH 4 in receiving phase and stirred for 4 hours.
In all these
optimum conditions the
percentage of Ni(II)
transported in acceptor
phase was about 88%
and the remaining
in donor phase
was about 8%.
On the influence
of Co(II) concentration on the
transport of Ni(II) using all optimum conditions. The concentration of Co(II) was 1.7
x 10-4 M
and greater than
1.7 x 10-4 M influence
for transport Ni(II)
to acceptor phase where significantly different from
percentage of Ni(II) at optimum conditions.
