In this work, Mn2O3/Fe2O3 (MFO) was synthesized and used to activate monopersulfate (MPS) for the degradation of ciprofloxacin (CIP). The effect several parameters studied on CIP degradation. Under optimum conditions (pH = 6.3 (natural pH), MFO 300 mg/L MPS 2 mM), around 92% decomposed. Nitrite, phosphate bicarbonate ions had a strong inhibitory MFO/MPS process while chloride nitrate neutral. catalytic activity also by other chemical oxidants such as peroxydisulfate, periodate, hydrogen...
Natural organic matter reacted with chlorine used for disinfection, and finally, trihalomethanes (THMs) are formatted. The main purpose of this study was to determine four THM concentrations human health cancer risk non-cancer assessment from exposure through oral ingestion, dermal contact, inhalation males females in Abadan. Two sampling sites were selected, five samples before after treatment by two different water systems (RO ion exchange) collected every week. Results showed that total...
The objective of this study was to investigate Artist's Bracket (AB) fungi for the removal Cr(VI) from aqueous solutions. effects pH, adsorbent dosage, temperature, contact time and initial concentration were evaluated. optimal pH value at 2. Moreover, results showed that adsorption decreased by increasing pH. absorption on AB can be described both Freundlich Langmuir isotherm models. In addition, pseudo-first-order pseudo-second-order kinetic model well onto AB.
In the current work, a rapid and simple dispersive liquid-liquid microextraction method (DLLME) was used to determine Bisphenol A (BPA). High performance liquid chromatography with photodiode-array detector (HPLC-DAD) coupled DLLME employed analyze BPA in food samples packaged including cans, paper boxes, glass jars. The calibration curve obtained be linear range 0.009–25 ngg−1 correlation coefficient of R2 = 0.9981. mean relative standard deviations (RSDs) 5.2% (n 3). limit detection (LOD)...
Biological wastewater treatment processes are among the environmentally friendly techniques for degradation of organic compounds. They also preferred to physical and chemical which due ability biological treat wide range compounds with lower operational costs. However, usually affected by variation in inlet quality quantity. In order investigate performance plant, various parameters case effluent such as COD, BOD, TSS, TDS etc. required be measured. Microorganisms bioreactors use enzymes...
Abstract Paraquat is a bipyridylium herbicide with high solubility in water, which widely used for aquatic weed control. The purposes of the present study were to introduce navel TiO 2 ‐based photocatalyst (SCS@Fe‐TiO ) and investigate its performance paraquat degradation from aqueous solution under visible light. response surface methodology (RSM) method was optimize pH, catalyst dose, initial concentration paraquat, irradiation intensity photocatalytic process. characterization results...
Furnace slag is a by-product of the steel industry containing high amounts silica. This inexpensive material existsin large quantities and can be used for synthesis zeolite. In present study, zeolite was synthesised using by hydrothermal method, it in biodiesel production from waste oil. Analysis physical chemical properties zeolitewas performed XRF, TGA, BET, FE-SEM,XRD EDAX.In catalysing production, effective parameters on including reaction time, molar ratio methanol to oil, catalyst...
This study aimed to assess the carcinogenic and non-carcinogenic health risks from heavy metals in five types of local universal tobacco through inhalation exposure.The demographic anthropometric data 200 participants were investigated concentrations tobaccos determined using inductively coupled plasma- optical emission spectroscopy (ICP-OES). Due lower employment rate, results showed females have a high tendency consume tobacco.The order was Fe > Mn Zn As Cd Cr Cu Ni Co. The sum...
Variation in hospital wastewater (HWW) pollutants and differences with municipal (MWW), make the use of biokinetic coefficients obtained from activated sludge MWW treatment unprofitable for designing, modeling evaluation biological processes HWW treatment. Since this study was conducted to evaluate performance a fixed bed bioreactor (FBBR) using rice husks as media treatment, new modified method also proposed estimation FBBR processes. For these purposes, five hydraulic retention times along...
Background: Sewage treatment leads to the production of large amount sludge, containing organic matter and nutrients considering requirements for recycling could be used as fertilizer. The sludge may also contain various pollutants that pose serious harm human health environment. This study aimed at characterizing industrial sewage evaluating its capability fertilizer with no or a minor pretreatment. Methods: sludge’s nutrient contents, heavy metals, microbial contaminants were determined...
