The modeling and analysis of transesterification reaction conditions in the selection of optimal biodiesel yield and viscosity
Abstract Among alternative fuels, biodiesel has been emphasized as a substantial candidate for diesel engines because of many advantages. However, the main shortcomings preventing more widespread use of biodiesel are high production cost and viscosity. In order to simultaneously overcome both of these shortcomings, the reaction conditions for the transesterification of waste cooking oil (WCO) were optimized using Taguchi and the full factorial design approaches. The analyses of...

Development of quantitative structure-property relationship model for predicting the field sampling rate ( R s ) of Chemcatcher passive sampler
Abstract Passive sampling technology has been considered as a promising tool to measure the concentration of environmental contaminants. With this technology, sampling rate (Rs) is an important parameter. However, as experimental methods employed to obtain the Rs value of a given compound were time-consuming, laborious, and expensive. A cost-effective method for deriving Rs is urgent. In addition, considering the great dependence of Rs value on water matrix properties, the laboratory...

Application of biochar in advanced oxidation processes: supportive, adsorptive, and catalytic role
Abstract The advanced oxidation processes (AOPs), especially sulphate radical (SO4•−)–based AOPs (SR-AOPs), have been considered more effective, selective, and prominent technologies for the removal of highly toxic emerging contaminants (ECs) due to wide operational pH range and relatively higher oxidation potential (2.5–3.1 V). Recently, biochar (BC)-based composite materials have been introduced in AOPs due to the dual benefits of adsorption and catalytic degradation, but the...

Recent developments in MnO 2 -based photocatalysts for organic dye removal: a review
Abstract The textile industry consumes a large volume of organic dyes and water. These organic dyes, which remained in the effluents, are usually persistent and difficult to degrade by conventional wastewater treatment techniques. If the wastewater is not treated properly and is discharged into water system, it will cause environmental pollution and risk to living organisms. To mitigate these impacts, the photo-driven catalysis process using semiconductor materials emerges as a...

Particulate matter on foliage of Betula pendula , Quercus robur , and Tilia cordata : deposition and ecophysiology
Abstract Trees in urban and industrial areas significantly help to limit the amount of particulate matter (PM) suspended in the air, but PM has a negative impact on their life. The amount of PM gathered on leaves depends on quantity, size, and morphology of leaves and can also be increased by the presence of epicuticular waxes, in which PM can become stuck or immersed. In this study, we determined the ability of PM to accumulate on leaves in relation to the species of tree and...
