“…All results presented in this report are average of replicate readings. The percentage removal of metal ions and the amount of metal ions adsorbed on orange peel at equilibrium (q e ) were calculated using the following equations: (2) where Co and Ce are the concentrations (mg/L) of metal ions initially and at equilibrium time, w is the weight of the adsorbent (g), while V the volume of the solution in litre (Bhattacharya et al, 2008;El-Nemr et al, 2008). The data obtained were tested using the linear forms of Langmuir, Freundlich and Dubinin-Radushkevich (D-R) isotherm, respectively, as shown in equation (3), (4), and (5) respectively;…”

“…By these methods, the treated oils can be used again in deep-fat frying process. Many reports have been appeared on the production of low cost adsorbents using cheaper and readily available materials (Babel and Kurniawan 2003;El Nemr et al 2008). In this regard, Sugar cane is one of the most common raw materials used in sugar and ethanol production.…”

The main goal of the current investigation was to use sugar cane bagasse ash (SCBA) and to compare its adsorption efficiency with Magnesol XL as synthetic adsorbents to regenerate the quality of used frying sunflower oil. In addition, to evaluate the effect of water washing process on the quality of used frying oil and the treated oil. The metal patterns of sugar cane bagasse ash and Magnesol XL were determined. Some physical and chemical properties of unused, used frying and used-treated sunflower oil were determined. Sunflower oil sample was heated at 180°C+5°C, then frozen French fries potato were fried every 30 min. during a continuous period of 20 h. Oil samples were taken every 4 h. The filter aids were added individually to the used frying oil at levels 1, 2 and 3 % (w / v), then mechanically stirred for 60 min at 105°C. The results indicate that all the filter aids under study were characterized by high levels of Si and variable levels of other minerals. The highest level of Si was recorded for sugar cane bagasse ash (SCBA) was 76.79 wt. %. Frying process caused significant (P≤0.05) increases in physico-chemical properties of sunflower oil. The treatments of used frying sunflower oil with different levels of sugar cane bagasse ash and Magnesol XL caused significant (P≤0.05) increase in the quality of treated oil, however the soap content of treated oil was increased, therefore, the effect of water washing process on the quality of used frying and used-treated sunflower oil was evaluated. The values of soap and Total polar compounds after water treatment were about 4.62 and 7.27 times as low as that for sunflower oil treated with 3 % sugar cane bagasse ash (SCBA). The results of the present study indicate that filtration treatment with different levels of sugar cane bagasse ash( SCBA) regenerated the quality of used sunflower oil and possess higher adsorbing effects than the synthetic filter aid ( Magnesol XL ) in removing oil oxidation products. The current study also recommends using hot water treatment for improving the quality of used frying oil.

In this work, feasibility studies of using a natural and low cost adsorbent; saw dust for the removal of Cr(VI), Ni(II), Fe(II) and Cd(II) from aqueous solution was carried out. The efficiency of the adsorbent was judged from the variation of the % adsorption with (i) contact time, (ii) adsorbent dose, (iii) initial metal ion concentration, (iv) effect of pH variation of the adsorbate solution, (v) activation of the adsorbents and (vi) particle size. Changes in the concentrations of the metallic ions after the adsorption process were monitored using Shimadzu AA650 Double-Beam Digital Atomic Absorption/Flame Spectrophotometer. Results suggest that the adsorbent employed in this work have the ability to remove the tested ions from their aqueous solutions with adsorption order onto the adsorbent varying according to Cr > Fe > Ni > Cd. Also for each ion there is an optimum pH for maximum adsorption beyond which the efficiency declined.
