Abstract
The present study was planned to remove the environmental pollutant (phenol). The
study was focused in many categories:
1. Determination of phenol in different samples of water as fresh
water (River Nile) and industrial wastewater (sugar factory).
2. Determination of phenol in soil and plant samples that were collected around the
investigated study.
3. Produce and characterized the activated carbon from some natural material (rice
strew, orange peels, and zeolite) by using chemical activation process.
4. Remediation of water polluted with phenol using activated carbon that produced
from different natural materials.
5. Remediation of water polluted with phenol using different natural materials under
different condition (pH, temperature, time, and dose of adsorbents).
6. Removal the phenol from industrial wastewater (vinasse) using some different
natural materials under the best conditions that have been studied previously.
7. Application of Langmuir equation.
The obtained results could be summarized in the following points:
1. Phenol Contents in Raw Materials
1- The levels of phenols determined in studied industrial wastewater drains and River
Nile water sample after mixing with industrial wastewater were higher than that of
River Nile before mixing with industrial wastewater which served as control.
2- Although there was a decrease in concentration of phenol in River Nile before
mixing with industrial wastewater as compared with after mixing with industrial
wastewater, the level of phenol in River Nile before mixing with industrial
wastewater was above critical ranges.
3- The concentration of phenol in sugar factory wastewater was higher than that
of river Nile after mixing with Industrial wastewater + Waste of small boats.
4-4- Progressive accumulation of the phenol was observed in the soil samples that
collected around the sugar factory compared with the soil samples far from sugar
factory.
5- Progressive accumulation of the phenol was observed in the plant sample that
collected around the sugar factory compared with the plant sample far from sugar
factory.
2. Phenol adsorption from polluted water
1. Removal of phenol was observed using some of natural materials.
2. The efficiencies of natural materials in removing of phenols are very
different.
3. Removal of phenol using some of natural materials at different condition is very
different.
4. Removal of phenol using different natural materials was in the
following increasing order: orange peels (86.54%) <Zeolite (92.18%) < rice strew
(94.15%).
5. Removal of phenol using different weights of rice strew and zeolite was
observed in the following increasing order: 1.0 g < 3.0 g < 5.0g
6. Removal of phenol using different weights of orange peels was
observed in the following increasing order: 5.0 g < 1.0 g < 3.0 g.
7. Removal of phenol using different times of rice strews, zeolite and orange peels
was observed in the following increasing order: 1 hr < 3 hr < 5 hr.
8. Removal of phenol using different temperature of orange peels was observed in
the following increasing order: 45 °C < 35 °C <25°C.
9. Removals of phenol using different temperature of rice strew were observed in
the following increasing order: 25°C<35°C< 45°C.
10. Removals of phenol using different temperature of zeolite were observed in the
following increasing order: 45 °C < 25 °C < 35°C
