Download Now White Paper: Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Concentration of residual filtrate C expressed in normal N was calculated as follows:. The iodine numbers which indicate the adsorptive capacities for low molecular weight substances wereand mg g -1 for bagasse, sorghum and millet straws, respectively.

To determine the adsorptive capacity of the active carbons produced, 1. Chemical activation is one of the possible methods for the production of active carbons Guo et al.

Fifty cubic centimeter of different solutions of methylene blue containing 0. Preparation of activated carbon from lignin by chemical activation. Three carbon dosages 2. aatm

The aztm 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 ]. Standard solutions of methylene blue were used for calibration. Enhancement of dyes adsorption efficiency on activated carbon from paper pulp sludge by chitosan coat and aeration [dissertation]. No other units of measurement are included in this standard.

In addition the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise. Production of active carbons from waste tyres-A review. Increased use of agricultural residues is an attractive addition to the utilization of wood and other carbonaceous materials for the production of active carbons.

High contents of volatile matter Therefore in order to be a good adsorbent, a solid must have a reasonably larger surface area and relatively larger pore network Barata-Rodrigues et al. Including, increasing Specific surface area and total pore volume. Each weighed sample of carbon was transferred to a clean, dry cm 3 Erlenmeyer flask equipped with a ground glass stopper.

Materials and Methods 2. If the document is revised or amended, you will be notified by email. The porous texture of the active carbons was characterised by asmt phase adsorption of iodine and methylene blue.

Conclusion, impregnation with Chitosan will have more amino ketone and aldehyde functional group while other functional group is not clearly different. The volume of sodium thiosulphate used was noted. Except active carbons from millet straws with iodine number ofcarbons from bagasse and sorghum straw gave iodine number within the reported values for carbons from pelletised straws and astj, that were activated physically during carbonisation Minkova et al.

This may have atsm from the increased amount of the intercalated phosphoric acid and various polyphosphates, which may produce larger pore volume and size when washed away from the carbons.

ASTM Method Numbers

The suitability of iodine and dyestuffs adsorption for characterizing active carbon have been implicated in several studies by Bhatia et al. The test is based on a three-point adsorption isotherm. The yields were obtained with optimum impregnation ratio of Enter your personal account email address to request a password reset: The larger size of atsm blue makes it suitable for estimating mesoporosity.
