“…Some studies showed that with an increase in adsorbent mass the amount of phenol adsorbed per gram of adsorbent decreases slightly. This may be due to the aggregation of adsorbent particles that leads to a decrease in effective surface area of adsorbent available for adsorption (Mane et al 2005). So, removal efficiency increases up to optimum dosage beyond which removal efficiency decreases.…”

Phenol is an environmental pollutant; the present study was conducted to examine the adsorption of phenol by rice straw. For this purpose raw (untreated), physically treated (boiled and dried) and thermally treated (heated at 230°C for 3 h to produce ash) rice straw were selected to determine phenol removal efficiency at different contact times and adsorbent dosages for 1 and \1 mm rice straw particles. Residual phenol concentrations were determined by colorimetric method. Highest 84 % of phenol removal was observed for thermally treated \1 mm rice straw particle. Equilibrium time was more than four hour. Percentage of removal of phenol increased as the adsorbent dose increase. The removal efficiency increase in the order of: raw rice straw \ physically treated \ thermally treated (ash) rice straw. Langmuir and Freundlich isotherm was developed for 1 and \1 mm particle size of thermally (ash) treated rice straw. Freundlich isotherm best fit the equilibrium data for 1 mm thermally treated rice straw. The results showed that thermally treated rice straw (ash) can be developed as a potential adsorbent for phenol removal from aqueous solution.

In this research, extraction and antioxidant activities of the oils from 15 varieties of Iranian date seeds were investigated. Khazravi variety (13.2%) and Kaliteh variety (6.2%) had highest and lowest yields of seeds with the average of 9.5% respectively. The highest and the lowest yields of oils were related to the Shavi-shirin variety (13.2%) and Piarom variety (6.4%) with the average of 9.5% respectively. Antioxidant activities of the oils were determined with DPPH radical scavenging assays. Results showed that Shavi-talkh and Estamaran varieties had highest and lowest activities with amount of 55.5% and 5.1% respectively (with average 30.1%). It was found that the some oils significantly reduced the concentration of DPPH free radical, with an efficacy higher than that of trolox (34.0%). These results may be encouraged interest in date seed oils for use in cosmetics, pharmaceuticals and food industries.

“…Functionalized MWCNTs and raw MWCNTs has active site with negative charged, the low or acidic solution environment can neutralize the negative particles, reduce the hindrance to diffusion of phenol ions and consequently increase the chance of their adsorption. High pH environment will lead to high concentration of [OH -], which increase the hindrance to the diffusion of phenol ions and thus reduce the chance of their adsorption [18,[23][24][25][26]. On the other hand, biochar which has positive active side will give a reverse effect to the low pH environment as high [H + ] will be introduce and increase the hindrance to the diffusion of phenol ions and reduce the adsorption capacity.…”
