OPTIMASI TRANSPOR ASAM SALISILAT MELALUI TEKNIK MEMBRAN CAIR FASA RUAH
Abstract: Transport of
salicylic acid can be done through bulk liquid membrane technique phase
consisted of a solution of salicylic acid 1.5 x 10-4 M as the source phase,
NaOH solution as feed phase and chloroform as the membrane phase. Concentration
of salicylic acid that transport to feed phase and remaining in the source
phase remaining was determined using UV-VIS spectrophotometer at 296.19 nm. The phenol concentration was
also determined using UV-VIS spectrophotometer with reagent 4-aminoantipirin at
510 nm. Technical operations assisted experiments with a magnetic stirrer
stirring at 340 rpm. The result showed that the optimum conditions for the
transport of salicylic acid at pH 2 in the source phase, 0.2 M NaOH
concentration for the feed phase, the transport time 60 minutes and salicylic acid which transport
to feed phase was 78.17%, while remaining in source phase of 10.89%. Phenol is
transported at optimum conditions where the source phase containing phenol at
pH 2 with concentration of 2.1276 x 10-4 M, 0.1 M NaOH feed phase, the
transport time of 120 minutes, stirring speed at 340 rpm and time of 15 minutes
equilibrium percentage obtained phenol phase transport to receiving 92% and the
percentage of remaining phenol in source phase of 3.21%.
