Standard solutions of methylene blue were used for calibration. Environmental Engineering Research ; 19 3: Next, activated carbon impregnated chitosan was carried out to adsorb CO 2.

The pictures were shown in Fig. This article has been cited by other articles in ScienceCentral. The measurement of iodine number corresponding to procedure established by the standard method ASTM D [ 5 ].

Print 1 2 3 4 5 page sstarting from page current page. Adsorption characteristic of activated carbon obtained from corncobs. It is expected to help combat global warming and climate change when the burning of the agricultural residues on farm lands are minimized.

Activated Carbon Applications

Production of active carbons was completed in 45 min. In porcelain crucibles, 0. Special emphasis on the preparation of active carbons from agricultural by-products has been given, due to the growing interest in low-cost active carbons from renewable safe copious supplies, especially s4607-94 applications concerning environmental monitoring. The measurement of specific surface area, pore volume, and pore size were determined by nitrogen adsorption-desorption isotherms at 77 K with discontinuous volumetric apparatus Quantachrome AUTOSORB 1 [ 6 ].

Each filtrate was titrated with 0. The active carbons obtained from low impregnation ratios 3 PO 4had strong influence on the yield of carbon.

The flasks were immediately stoppered and shaken vigorously for 30 sec. No other units of measurement are included in this standard.

Assessment of active carbon derived from maize cobs for decolorising textile effluents. However, adsorption was nearly all time linear below initial methylene blue concentration of 1. No further reproductions authorized. It does not necessarily provide a measure of the carbon’s ability to absorb other species.

The amount of constituents removed and the adsorptive capacity is calculated from a Freundlich isotherm ASTM D, The yields were obtained with optimum impregnation ratio of Effect of adsorbate polarity on thermodesorption profiles from oxidized and metal-impregnated activated carbons. The impregnation ration, which was controlled by varying the proportion of H 3 PO 4 used for activation, had a strong influence on the yield of active carbon.

Fifty cubic centimeter of different solutions of methylene blue containing 0. Preparing activated carbon from various nutshells by chemical activation with K 2 CO c4607-94. For the applications involving removal of colour, taste, odour and toxicants from aqueous matrices, adsorption capacity of active carbon may be determined by aqueous phase isotherm technique ASTM D, Scanning Electron Microscope Studies SEM technique was applied in order to study regarding surface morphology dd4607-94 adsorbent before and after impregnation with chitosan solution.

Standards Subsctiption may be the perfect solution. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Two qubic centimeter of freshly prepared starch indicator solution was added and the titration continued with sodium thiosulphate until one drop produced a colourless solution.

The straws and bagasse were air-dried for 3 months on plastic mesh, to ensure adequate drying for easy milling and avoid the loss of carbon residue due to oven-drying. The volume of sodium thiosulphate used was noted.

Anomalous adsorption of iodine on activated carbon.
