“…Figure 5a and Figure 5b shows IR spectra of TRH 700 and after oil adsorption, respectively. The band with a maxi mum at 1089 cm -1 is connected with vibrations of the C-OH bond and it is dominating in kind and position, as this wave number is characteristic of the stretching vibrations of the siloxane groups [14,15]. After oil adsorption, FT-IR measurement shows (Figure 5b) the pattern with much strong peaks at 2923 and 2853 cm -1 at high intensity, suggesting the oil component combining with hydrophobic groups of heat-treated rice husk [16].…”

Rice husks, an agricultural waste, were thermally treated and evaluated as an adsorbent for oil with the goal of being used as a remediation strategy for oil spills of oil based products. The oil sorption capacity was examined of thermally-treated, carbonized rice husks which are mainly composed of silicates. Results showed that the oil sorption capacities of the carbonized rice husks prepared at 700°C is 16 g/g for heavy crude oil. The microstructure and morphology of the carbonized rice husks were investigated by FTIR spectrometry and Scanning Election Microscope (SEM).

Abstract. This research studied production of activated carbon (AC) derived from tamarind pods damaged by mold. Folk wisdom kiln which manufactured from an oil tank size of 200 L was used for pyrolysis and carbonization of tamarind pod derived from sweet and sour tamarinds. The AC was produced by using chemical activation and thermal activation at the optimal condition. Then the physical and chemical properties of the AC were investigated. From the study, it was found that optimal condition for charcoal carbonization of the tamarind pod was 400 0 C for 4 hrs. The optimal condition for thermal activation was 600 0 C for 1-2 hrs. The phosphoric acid (H 3 PO 4 ) showed higher effectiveness for activation than distillation water (H 2 O), potassium hydroxide (KOH) and zinc chloride (ZnCl 2 ). The produced AC has specific surface area of 851.58-910.31 m 2 /g (BET Theory), a pore volume of 2.24-2.32 cm 3 /g with an average pore radius of 50.90 to 52.53 Å, iodine number of 613.9-654.8 mg /g, phenols adsorption of 61.7-83.1% and apparent density 0.4528 g/cm 3 . The results from proximate analysis shown that the AC has the moisture content of 6.81-7.54%, the ash content of 6.58-7.31%, the volatile matter of 38.26-40.12% and the fixed carbon of 52.57-55.16%. The performance of the AC for acetic acid adsorption according to the Langmuir and Freundlich isotherm exhibited a monolayer adsorption isotherm and the AC adsorbed the acetic acid well and strength. Therefore the produced AC can be further used for filter material in small water treatment.

“…It was chosen because of its granular structure, chemical stability and its local availability at very low cost and there is no need to regenerate them due to their low production costs. The main constituents of rice husk are: 64-74% volatile matter and 12-16% fixed carbon and 15-20% ash [2]The rice husk composition are: 32.24% cellulose, 21.34% hemicellulose, 21.44% lignin, 1.82% extractives, 8.11% water and 15.05% mineral ash (Govindarao 1980;Rhman et al 1997;Nakbanpote et al 2000). The mineral ash is 94.5-96.34% SiO2.…”

Abstract-To show that rice husk could be employed as low-cost and effective adsorbent for the removal of direct red 23 from dye effluent and also to study the effect of concentration of dye solution and the effect of amount of adsorbent on the percentage removal of dye. Azo dyes and their degradation products such as aromatic amines are highly carcinogenic. Adsorption of dyes is a new technology for treatment of waste water containing different types of dyes. Adsorption process is adopted for removal of direct red 23 dye from the dye effluent using rice husk as the adsorbent in treated and untreated form. The process involves: washing and drying of rice husk at 105°C, followed by soaking in 0.6 M citric acid for 2 hours and heated to 120 °C. Further it is dried and washed repeatedly to obtain treated rice husk. This treated and untreated rice husk are used for removal of direct red 23 dyes. Dye solutions of different concentrations were prepared and a known amount of adsorbent were added to study the Effect of concentration of dye solution and effect of amount of adsorbent on the percentage of removal of direct red 23.Index Terms-Direct red dye, rice husk, adsorption, effluent treatment, microporous. I. INTRODUCTIONAzo dyes and their degradation products such as aromatic amines are highly carcinogenic [9]. Adsorption of dyes is a new technology for treatment of wastewater containing different types of dyes [7]. The goal of this research is to develop a new and efficient adsorbent of direct dyes. Thus, rice husk, a commonly available agriculture waste, was investigated as viable materials for treatment of synthetic Direct F. Scarlet (Direct Red 23) containing industrial wastewater. Rice husk has many advantages such as its granular structure, chemical stability and its local availability at very low cost and there is no need to regenerate them due to their low production costs. The main constituents of rice husk are: 64-74% volatile matter and 12-16% fixed carbon and 15-20% ash [1]. Hence rice husk can be used as an effective adsorbent. Proper treatment of the dye plant effluent is thus, a matter of concern before discharge. This led to an intensive search for the best available technology, which can be used for the removal and remediation of dyes. In addition, it makes the treatment of industrial effluent to be an important target for industry and environment protection. Different treatment methods are described in the literature, including filtration, flocculation, chemical precipitation, ion exchange, membrane Manuscript received July 17, 2012; revised October 23, 2012.

Practically, dye removal process requires the following potential advantages for the adsorbent: 1) a large accessible pore volume, 2) hydrophobicity, 3) high thermal and hydrothermal stability, 4) no cata...
