A chitosan membrane modified with chloroacetic acid with heparin (hep) and polyvinyl alcohol (PVA) has been successfully prepared. Chitosan was modified with chloroacetic acid through a nucleophilic substitution reaction to form N-carboxyl methyl chitosan (N-CMC) and then combined with PVA. N-CMC/PVA grafting with heparin was conducted using the immersion method and produced N-CMC/PVA.g.Hep membrane. This study aims to obtain a membrane with the best chemical and physical characteristics and the highest creatinine transport. Membrane characterization includes water absorption test, tensile strength, thickness, biodegradation, resistance to pH, and transport of creatinine and vitamin B12. Chemical characterization of active groups and morphology using FTIR and SEM. The characterization results show that the reaction of grafting chitosan using chloroacetic acid produces N-carboxymethyl chitosan (N-CMC). The N-CMC/PVA membrane has a creatinine transport capacity of 19.61%. The N–CMC/PVA.g.Hep membrane has a creatinine transport capacity of 24.81%. Supporting PVA improves the hydrophilicity and mechanical strength of the membrane.

A chitosan-polyvinyl pyrrolidone K-30 (Cs-PVP.K30) membrane was prepared as a heterogeneous catalyst supporting membrane in the transesterification process in the production of biodiesel from palm oil and methanol through the blend reaction between chitosan (Cs) and polyvinyl pyrrolidone K-30 polymer (PVP K-30). Several membranes were characterized by their physicochemical and catalytic properties. Based on physicochemical data, it was found that including the carbonyl group from PVP K-30 into the chitosan framework correlated with an increase in porosity, hydrophilicity, water absorption, and the degree of swelling of the membrane. The results of the analysis using Fourier Transmittance Infra-red (FTIR) showed the spectra of carbonyl (-C=O) and hydroxyl (-OH) groups at wavenumbers 1648 cm-1 and 3363 cm-1, which shows that the reaction of chitosan alloy with PVP K-30 has been successfully carried out. The catalytic site of the Cs-PVP K30-NaOH membrane in the biodiesel production process was studied under several conversion conditions. It was found that the conversion of biodiesel reached 93.90% with a reaction time of 90 minutes, a temperature of 65°C, and an oil/methanol mole ratio of 1:7.

Copper and sulfur modified TiO2(Cu-S-TiO2) photocatalyst was successfully synthesized using TiCl4, Cu(NO3)2.3H2O and H2SO4 as precursors by the sol-gel method andcalcination at 450°C for 4 hours. The synthesized photocatalyst was characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS), Diffuse Reflectance Spectroscopy (DRS), Brunauer Emmett Teller (BET) method. The XRD results showed that the Cu-S-TiO2 photocatalyst had an anatase phase with a crystal grain size of 17.54 nm. However, the SEM image of the modified TiO2 showed inhomogeneous phase due to the crystal clustering of imperfect homogenization during the synthesis and sintering processes. The patterns of EDSof Cu-S-TiO2depicted the elements of Ti, O, Cu and S with doping of Cu and S c.a. 7 and 1%, respectively. Analysis using DRS UV-Vis showed Cu-S-TiO2 was able to shift the absorption of the TiO2 photocatalyst wavelength to the visible region with a band energy gap of 1.9 eV. The BET analysis results showed that the specific surface area (SBET), pore volume (Vp) and average pore volume radius (Dp) were measured from large Cu-S-TiO2, therefore Cu-S-TiO2 had good physicochemical and photocatalytic properties. The photocatalytic activity of 0.1 g Cu-S-TiO2 with 15 Watt tungsten light irradiation for 4 h was able to degrade 50 mL remazol black B 10 mg/L c.a. 92.60 %.

Polyvinyl alcohol (PVA) modified chitosan-carboxymethyl chitosan (CMC) membrane has been successfully fabricated and used as a dialysis membrane. This research aims to examine the manufacturing process, characterization, and dialysis performance of CMC and PVA-modified chitosan membranes. The membrane used the phase inversion method in acetic acid solvent with 5 CS:CMC: PVA dope compositions. Based on FTIR data, the modification process did not produce new spectra. Furthermore, the interaction produces a membrane with higher physical characteristics in terms of porosity, swelling, water uptake, hydrophilicity, and pH resistance values, which increase by 1.5–115%. Meanwhile, chitosan modification makes the membrane structure different from the original, requiring a longer degradation time. The modification also increased the permeation ability of urea by 17–65% and creatinine permeation by 20–62%. Membranes have the ability to be used more than once.

Study on decolourization of remazol black B (RBB) solution has been performed in a scale up reactor. As an artificial waste, the dye sample that contains azo groups is difficult to decompose under ordinary environmental conditions so it requires further treatment before discharging to open aquatic system. Many efforts have been reported and further developed toward other azo dyes. One of an outstanding approach is Fenton method. This study modified the method with PbO2 rather than Fe2+. In this modification, the dyestuff was degraded by radical •OH resulting from reaction between H2O2 and Pb2+ ion generated from PbO2. In Preliminary works, decolourization was performed and optimized in lab-scaled. Analysis were conducted and the best condition was applied to decolorize the sample in a scale-up size. Characteristics of the reactor was also determined. Results showed that at optimum condition, 100 mL of 50 ppm remazol black B was decolorized up to 98.82 % within 15 minutes. On scale up to 1 L-sized reactor, within the time highest percentages of remazol black B decolourization was reached 82.02 % by addition of 10 % H2O2 and COD decrease to 98.96 %. In the 1 L reactor, RBB sample with concentration of 50 ppm, PbO2 1 gram and H2O2 10 % obey the proposed decolourization equation of D = -0,0011x2 + 0.5705x – 0.6788 with x = volume peroxide (in mL), D = percent of decolourization.

Evaluation character of chitosan membrane-succinate / poly vinyl alcohol-poly ethylene glycol (PVA-PEG) were prepared in acetic acid solvent through a phase inversion method has been performed. The study began with the preparation of crosslinked chitosan compounds with succinic acid, followed by preparation into membrane by combining PVA-PEG. Character analysis of the resulting material using FTIR, EDX, TGA, water absorption test, tensile strength, membrane hydrophilicity. The ability of membrane permeation was tested against creatinine. The results showed that the succinate had reacted with chitosan. Chitosan modification through cross link and polymer alloys increases tensile strength and membrane strain of 1.7-2.5 x of pure chitosan membrane. In addition, the modified membrane also has higher water absorption and hydrophilicity values than the unmodified membrane, and this implies the ability of membrane-induced creatinine permeation. Permeable permeation values were 13.8% in chitosan, 24.84% on chitosan-succinate and 25% in chitosan-succinate / PVA-PEG. Chitosan-succinate membranes have the ability to use more than 4x repeated use.
