TRANSPOR KREATININ MELALUI MEMBRAN KITOSAN DAN N-DODESIL KITOSAN
A study on creatinine transport through membranes based on chitosan and N-dodecyl chitosan and its blend had been conducted. N-dodecyl chitosan was synthesized by alkylation with the reflux process. Membranes were prepared by inversion phase technique and MIP (molecularly imprinted polymer). Princip...

description |
A study on creatinine transport through membranes based on chitosan and
N-dodecyl chitosan and its blend had been conducted. N-dodecyl chitosan was
synthesized by alkylation with the reflux process. Membranes were prepared by
inversion phase technique and MIP (molecularly imprinted polymer). Principle of
phase inversion technique is change liquid phase to solid phase. Principle of MIP
technique is templating molecules into membrane. Membranes morphology was
characterized using SEM, water absorption was calculated and the stretch and
tensile strength were measured using Universal Testing Machine.
The creatinine transport was prepared with chitosan, N-dodecyl chitosan
and its blend membrane using chamber, membrane separates the source and
acceptor phase. Variables in this research were the concentration of creatinine as
source phases, technique of membrane preparation and the composition of the
chitosan membrane. The source phase were prepared 50 mL of creatinine 70, 100
and 130 ppm and acceptor phase 50 mL of distilled water, both of phase adjusted
to pH 7.4. The concentration of creatinine after transport in the source phase and
the acceptor phase was determined using picric acid under alkaline conditions
using UV-Vis spectrophotometer at λ 490 nm.
The results of FTIR showed the success of the alkylation, be marked by
the loss of bending vibration absorption of primary amines (-NH2) and appearance
of aliphatic C-H stretching vibration absorption of dodecyl groups. The
morphology of the MIP membranes appear more solid than PI. MIP chitosan
membrane is the highest of tensile strength and % strain, 53.7 MPa and 17.35%
respectively, while the lowest tensile strength is the MIP N-dodecyl chitosan with
14.1 MPa and the lowest strain was PI N-dodecyl chitosan membran of 5.35%.
MIP chitosan membrane has the highest water absorption, 93.24%, while the
lowest absorption was MIP N-dodecyl chitosan membrane at 61.71%. The results
of creatinine transport show that concentrations of source phase using membrane
MIP in the early transport was lower than PI membranes. |
