in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
Background and purpose: Nitrobenzene (NB) as the main material of synthetic fuels, cleaners, rubber and explosives is discharged into the environment and groundwater in large-scale. This compound is considered as a persistent organic pollutant with high toxicity and stable chemical structure which can cause serious risks for human health and ecosystem even in low concentrations. Therefore, the ...
Introduction: Emission of volatile organic compounds through industrial processes to the environment has been received more attentions currently. Photocatalytic oxidation process as a new emerging technique in air purification can be substituted for conventional techniques such as activated carbon adsorption. In photocatalytic oxidation process, pollutant molecules decompose to water and carbo...
The elimination of organic contaminants from natural resources is extremely important to ensure their (re-)usability. In this report, the degradation a model pharmaceutical compound, theophylline, compared between and laboratory-controlled environments. While concentration H2O2 variably affected efficiency (approximately 8 20 min for complete degradation) in photo-irradiation experiments, inorg...
