Experimental methods in chemical engineering: Ultraviolet visible spectroscopy—UV‐Vis

UV-vis spectroscopy is an inexpensive, simple, flexible, non-destructive, analytical method appropriate for a wide class of organic compounds and some inorganic species. UV-vis spectrophotometers measure the absorbance or transmittance of light passing through a medium as a function of the wavelength. Chemical engineers apply it for quantitative analysis, to derive liquid phase reaction kinetics, and to identify the mechanism at the molecular scale. High performance liquid chromatography and ultra-high performance liquid chromatography integrate UV-vis detectors to identify and quantify the concentration of compounds in liquid streams. Combining these techniques with mass spectrometry facilitates identifying all species. UV-vis diffuse reflectance spectroscopy is a variant with enhanced scattering properties that measures the properties of solids and powders. A bibliometric analysis of the 10 000 most cited papers referring to UV-vis (2016 and 2017) groups research in four major clusters: nanoparticles and nanostucutres; photocatalysis and water treatment; crystals, complexes, and derivatives; and Ag and Au nanoparticles biological interaction.

“…Since there is no solid byproduct formation and no occurrence of phase transfer of the pollutants, advanced oxidative processes can also be considered clean (green) technologies. [8,12] Some of the technologies with the potential to remove or degrade sunset yellow dye include adsorption, [5,13] Fenton-like catalysis through pulsed high-voltage discharge, [14] catalysis using zero-valent metals under ultrasonic irradiation, [15] photocatalytic degradation, [16] nanofiltration, [17,18] anodic oxidation, and electro-Fenton, [10,12] photoelectro-Fenton, and solar photoelectro-Fenton processes, [10] among others.…”

Effectiveness of ozonation and catalytic ozonation (iron oxide) in the degradation of sunset yellow dye

et al. 2020

Azo dyes present in industrial effluents represent a hurdle that regular treatments cannot overcome. In this study, the application of ozone and a catalytic (iron oxide) ozone treatment were proposed as a means of degrading aqueous sunset yellow dye. In order to understand the factors involved, a rotatable central composite design was applied using the variables time, initial dye concentration (C 0), pH, ozone inlet concentration (O 3), and mass of catalyst, which varied in each case. All variables were significant in colour removal. Extremes in pH, lower C 0 , and higher ozone concentrations are conditions that favour dye degradation. A complete colour loss occurred for certain combinations of these parameters. The application of iron oxide as a catalyst did not present a satisfactory improvement in the reaction rate. Chemical oxygen demand and total organic carbon showed minimum values of 80% and 78%, respectively, for the worst experimental conditions (pH 7.0, C 0 of 45 mg • L −1 , and 5 g O 3 • m −3), while their values were 88% and 83% for the best conditions applied. There was no immobilization of Artemia salina nauplii, even for the experimental run where the maximum concentration of dye of the set was used (45 mg dye • L −1). Ozonation is a promising alternative in the degradation of aqueous sunset yellow dye, being favoured in acidic or basic media, which is especially important since food effluents usually present low pH and show low toxicity. The mathematical model proposed can be useful in the design of wastewater treatment processes.

“…The main drawback of most of these methods is producing dye wastewater sludge [98], [99]. High voltage pulsed electric discharge is one of the effective advanced oxidation processes for sunset yellow wastewater decoloration [100]. Zho et al designed a point-to-plane electrode system and a copper mesh-plate discharge system in [100] to degrade sunset yellow with an initial concentration of 50 mg/l in 1L solution.…”

A Review of Pulsed Power Systems for Degrading Water Pollutants Ranging From Microorganisms to Organic Compounds

2019

View full text Add to dashboard Cite

Water quality improvement and collecting safe water are two of the paramount concerns in today's world. Numerous water treatment and pollutant removal processes are introduced that vary with the type of pollutants. Among the proposed pollutant degradation methods, pulsed power is one of the effective methods that can be applied not only to degrade a wide range of contaminants but also to address the environmental issues associated with water treatment chemicals. The effectiveness of the pulsed power technology in water treatment was studied for a wide range of pollutants including microorganisms, nutrient pollution, emerging pollutants, and organic pollutants. This paper presents a review of pulsed power systems developed for organic and inorganic pollutants degradation in different water treatment applications. Also, it presents the effectiveness of several factors like the electrical characteristics of the pulse voltages and treatment time on degradation rates of different pollutants.
