Abstract

Polyurethane (PU) membranes were prepared from red seaweed (Gracilaria sp.), castor oil, Toluene Diisocyanate (TDI), and added benzoyl peroxide (BPO) additive to improve membrane performance. The membrane is applied for the adsorption of ammonia in the solution. FT-IR analysis showed the presence of functional group N = C = O at a wavenumber of 2276 cm-1 and the O-H functional group at a wave number of 3373.50 cm-1, indicating the urethane group's formation has been formed during membrane polymerization. SEM images showed the morphological structure of the PU membrane, where the more open structure of the PU membrane by the addition of BPO. The DSC and TGA results showed the membrane's thermal stability with the addition of BPO. The PU membrane has an optimum contact time for ammonia uptake of 40 minutes. The adsorption isotherm of ammonia by the PU membrane follows the Freundlich isotherm model. The adsorption capacity of the PU membrane with the addition of BPO additives was 13.2 mg/g, which shows that the adsorption capacity of the PU-BPO membrane has a better performance than a membrane without the addition of the BPO. The PU-BPO membrane could be used as an alternative method of ammonia removal.

Abstract

The purpose of this study was to determine the effect of -tocopherol on the mechanical, thermal, and morphological properties of polypropylene-montmorillonite (PP-MMT) nanocomposites. The preparation of polypropylene-montmorillonite (PP-MMT-AO) nanocomposites was carried out on PP compositions; PP-g-MA; MMT-octadecyl amine; AO is 80;10;10;5 and the PP-MMT nanocomposite composition is PP; PP-g-MA; MMT-Octadecyl amine: 80;10;10. The SEM results showed that polypropylene, MMT, and the antioxidant -tocopherol could be exfoliated and intercalated to produce compatible nanocomposites. The mechanical and thermal test results showed that the PP-MMT-AO nanocomposite had higher mechanical properties and thermal stability than the PP-MMT nanocomposite. Based on the FTIR test and degradation test on PP-MMT and PP-MMT-AO films which were carried out for up to 15 days and 30 days showed that the PP-MMT-AO nanocomposite against UV light was given, this shows that -Tocopherol can prevent oxidation reactions polypropylene.

Abstract

Modification of montmorillonite with chitosan as an adsorbent of mercury (Hg) metal has been carried out. This study aims to determine the characteristics of the adsorbent, the optimum adsorption capacity of Hg metal, and its adsorption isotherm equation. The optimum conditions for Hg metal adsorption are determined by varying the contact time and pH of the solution. Variations in adsorbate concentration are carried out to determine the adsorption isotherm. Characterization of the adsorbent using FTIR shows the presence of -OH, Si-O, Al-O, C-C, and N-H groups. The optimum conditions for mercury metal adsorption by montmorillonite modified with chitosan occur at a contact time of 80 minutes, and a pH of 4. The adsorption process of mercury metal ions using montmorillonite adsorbent modified with chitosan satisfies both isotherm models, namely the Langmuir and Freundlich isotherms with R2 values of 0.971 and 0.967 respectively, and a maximum adsorption capacity of 13.513 mg/g. The regeneration test showed that the adsorbent can be reused for the absorption of mercury metal ions.
