Abstract

One important pollutant in water resources is toxic substance “phenol” and its derivatives. PNP is the most toxic one in its group. It is very important to be omitted. A quantity of studies has been made to omit PNP in polluted waters and industrial wastewaters by activated carbon, nano tube carbon and… Aim of this study is separating PNP in stable temperature conditions in a bed of activated carbon with nano pores and modifying structure of these pores with chemical materials. At first amount of absorption of PNP by primary AC was measured. In second stage the AC modification and parameters like concentration of PHOSPHORIC ACID, pH, temperate of oven &… were investigated. In researching concentration of H3PO4 from 6% to 35%, it was observed that the best concentration is 6% with absorption rate of 95.5%. The best temperature time is 550oC in 40 minute. pH was investigated from 1 to 5 and the result was modification of pH in 1,2 with 99.5%. The kinetic of adsorption in different times of AC showed that max absorption with concentration of 10000 ppm achieved in 180 minutes and more than 90% of absorption accrued in the first 60min. Max capacity of absorption of AC accrued in this research was 142.22mg/g. And there was done a comparison between capacity of absorption of modified AC, SWNT, MWNT, nano article of iron & the primary AC. The acquired amounts show superiority of activated modified carbon than other mention absorbers. In this research capacity of absorption in comparison with reported amounts are good and in competing.
