Scientific Approach

A scientific approach has been adopted in this research work to develop an antibacterial composite material by synthesizing the zinc and oxide together along with activated composite of carbon. NH3, H2O2, ZnO, AC and H2O were used in this context. Embedded together to convert the zinc oxide to activated carbon. The 2.5 g of zinc oxide along with 45 mL of ammonia mixed with 4 mL of H2O2. After that 250 g of activated carbon along with precursor solution was soaked for a period of 3 h. Immediately, after soaking the solution was kept for drying at room temperature for a period of 12 h. After drying, the product was sintered in the sintering furnace at a temp: of 248 °K (120 °C) for a soaking period of 2 h. The morphology was analyzed with the help of XRD and SEM. The XRD peaks clearly shows the zinc oxide and activated carbon product and also the SEM micrographs reveal the porous structure of the composite of ZnO activated carbon. It is concluded that the antibacterial activated carbon composite of zinc and oxide was successfully developed and can be used for water filtration.

Research on  photodegradation of textile dyes  of methylene blue (MB) and congo red (CR) using ZnO-Activated Carbon composite and ultraviolet (UV) light has been done. This research included synthesis zinc oxide (ZnO), synthesis ZnO-Activated Carbon, and the application of composite to degrade textile dyes of MB and CR. In this research studied the effect of pH, concentration and time of UV radiation  towards photodegradation percentages  of dyes. Then it determined the rate and the effectivity of photodegradation of MB and CR dyes using ZnO-Activated Carbon composite. The result showed that  photodegradation of MB reach optimal condition at pH 11 with radiation time 4 hour, whereas CR is at pH 5 with the same radiation time. The more initial concentration of MB and CR applicated, the lower of photodegradation percentages. Constanta of photodegradation rate of MB and CR dyes using ZnO-Activated Carbon composite are 0.8316 and 1.4938 hour-1 respectively. ZnO-Activated Carbon composite as a photocatalyst can degrade effectively MB and CR dyes with photodegradation percentages of 99.40±0.23 % and 99.61±0.24% respectively.

Polysulfone/Activated Carbon (PSF/AC) composites in bead form were prepared for Rhodamine B sorption. The scanning electron microscope (SEM) shows that pure PSF bead is smooth surface while PSF/AC bead presents the pore distribution. FT-IR spectra indicate the existence of AC on the PSF/AC bead surface. Under adsorption test of Rhodamine B, it was found that an increase in the AC content in PSF solution results in an increase in the percentages of dye adsorption from 1.38 % to 71.56% for pure PSF bead and PSF/AC added with 4 wt% of AC, respectively.

<p>A composite of γ-alumina and activated carbon made of cassava peels was studied in terms of its pore structures and its properties. The objective of this study was to determine the interaction and structure, as well as the character and pore size of γ-alumina – activated carbon composite.</p><p>Carbon made of cassava peels was activated by H<sub>2</sub>SO<sub>4</sub> and its activities were tested according to the Indonesian Industrial Standards (SII). The addition of activated carbon into γ-alumina made in variations of 10, 20, 30, 40 and 50 % w/w, of the total weight of 10 grams. The composite of γ-alumina - activated carbon was characterized by FTIR, SAA (Surface Area Analyzer), XRD, and determination of Hysteresis Loop composites.</p>The greater addition of activated carbon to γ-alumina causes intermolecular interactions between –O-H groups form rehydrated hydrogen bonds in the composite is greater. The structure of γ-alumina in the composites remain intact although the percentage of activated carbon in composite is large. The total pore volume and surface area using the BET method of the composite decreases with increasing activated carbon percentage. The greater addition of activated carbon to γ-alumina causes size of mesoporous composites decreased with the characteristic of a composite formed is closer to the activated carbon.
