Phenols Degradation by Fenton Reaction in the Presence of Chlorides and Sulfates
Siedlecka et al. (2005) also studied a series of phenol compounds present in wastewater. These compounds, as mentioned above, are widely used therefore are commonly found in wastewater derived from different industries such as petrochemical, food or resin manufactured.
Since common biological treatment for these kinds of compounds is not feasible, is important to develop new technologies to treat these recalcitrant molecules.
In this paper the authors studied the influence of chloride and sulfate anions on Fenton’s reaction of three representative phenol compounds: phenol, 2-chloro- and 2-nitrophenol.
The batch experiments were carried out with the phenol solution in…
wheat kernels in 150 μm sieve; Wwheat in 75μm sieve = weight of wheat kernels in 75 189 μm sieve; Wpan =
190 weight of empty pan; and Wmaize meal = weight of maize flour.
191 Determination of Crude Protein
192 The crude protein content of the roasted maize was determined in duplicate by Dumas combustion
193 method as described in AACCI Approved Method 46–30.01 (AACC, 1999) using a Leco, model
194 FP-528 (Leco Africa, Kempton Park, South Africa). Calibration of the instrument was done using
selected variables such as pH of phenol solution, concentration of hydrogen peroxide, concentration and the volume of phenol to be treated was studied to find the degree on the degradation of phenol. The influence of these variables on the degradation of phenol using H2O2 by interpreting the TOC results is presented in the following sections.
3.1 Effect of pH
The phenol degradation with different pH is shown in Figure 3. As it is clearly seen, a higher pH favors the removal of phenol in…
the control experiments, the interaction between the Calcium Chloride and phenol red are responsible for the high temperature change in the overall reaction. After doing a control experiment with Sodium Bicarbonate and phenol red and noticing that the temperature got colder, only one other chemical mixed with phenol red could be responsible for the warm temperature change that chemical being Calcium Chloride. There was a temperature change that was observed during the individual control labs as…
It has been reported that the use of phenol is the surgical procedure of skin peeling can produce cardiac arrhythmias although specifics of dose received were not determined and would be expected to be extremely high (Office of Environmental Health Hazzard Assessment, 2015). In 1985 a group of iron and steel foundry workers with multiple chemical and aerosol exposures were examined and found to have more respiratory systems in the phenol exposed group (Office of Environmental Health Hazzard…
Observe Ligand-Protein Interaction using Gel Filtration Chromatography
(Phenol Red Binding to Bovine Serum Albumin)
Serum albumin is often known as blood albumin, and is the most abundant protein in humans and other animal plasma. Serum albumin is also known as a carrier protein by non-specifically binding several biomolecules. It is essential for maintaining the osmotic pressure that is needed for body fluids distribution between body tissues and intravascular compartments.…
They used TEM, BET specific surface area, X-ray photoelectron spectrum (XPS) and X-ray diffraction (XRD) to analyses physico-chemical properties of the catalyst. In addition, the catalytic activity, dimer inhibition, stability, and a kinetic model are analyzed to gives further evidence of the effectiveness SCWG of phenol. The results of their experiment show that Ru/CeO2 effectively assisted for converting phenol to gaseous fuels CH4 and H2 in supercritical water. Moreover, The efficiency of…
The ferric chloride test is used to determine the presence of phenols in a given sample or compound (for instance natural phenols in a plant extract). Enols, hydroxamic acids, oximes, and sulfinic acids give positive results as well. The ferric chloride test can be used to detect metabolites in urine in case of inborn error of metabolism such as phenylketonuria. In addition,the Ferric Chloride test can be used to detect salicylates in urine after an aspirin overdose.1
This test is designed to tell whether or not an organism can ferment glucose, reduce sulfur, and produce gas. The semi-solid, slant TSI test starts out as a burnt orange color and also contains phenol red, which is a pH indicator. When glucose is fermented, the solution becomes acidic, causing the TSI tube to turn orange. If the organism is unable to ferment glucose, the amino acids that are present in the TSI tube are fermented, causing the tube to turn pink. If sulfur can be reduced by the…
has been extensively used in conventional
medication, and a huge number of feed additives based on this molecule are at
present commercially accessible.
Thymol (2-isopropyl-5-methylphenol) is found in thyme essential oil which
is the main monoterpene phenol and isomer of carvacrol. Thyme is a labiatae plant
which essential oil has demonstrated antiseptic, antispasmodic, antiinflamatory,
immunomodulatory, antioxidant, antibacterial and antifungal properties.
