دراسة كربنة نواتج التحلل القاعدي لأخشاب التوث و تأثيرها على مواصفات الكاربون المحضر

الملخص EN

The study involved hydrolysis of the wood in basic medium using a measured amount of 50% NaOH.

The mixture was refluxed for four hours, cooled to room temperature.

The hydrolysed product was allowed to settle for 24 hr.

The liquid was discarded and the solid remained was filtered and washed with water till huetralisation.

The remained materials were treated with NaOH in a ratio of (1/0.5, 1/1, 1/1.5, 1/2 solid/NaOH).

The mixture was heated at 300-350oC for about four hour.

The carbonisation process was continued to about 500oC, till all vapours and gases were diminished.

The product carbon was activated using excess amount 30% HCl.

The mixture was filtered and washed with distilled water till the product is nuctral.

The carbon was dried at 120oC.

the activated carbon prepared was further used in the adsorption of iodine and nethylene blue.

Other variables such as density, humidity and ash content were determined.

The result of the prepared carbon and that of untreated wood in addition to standard sample were comparable
