Special Issue Information

Dear Colleagues,

Green chemistry (GC) aims at the development of chemicals and chemical processes to reduce the impact on human health and the environment. GC seeks environmentally friendly alternatives to reduce hazards associated with chemical activities that are essential to the world economy and modern societies. The twelve principles of GC emphasize thinking in terms of sustainable design criteria and have been demonstrated to be the source of innovative solutions to a wide range of problems.

In the context of analytical chemistry, some well-stablished methods require hazardous chemicals and/or high energy demand for sample preservation, pretreatment, calibration, and analyte determination. Frequently, analytical methods yield large amounts of waste with even higher toxicity than the target analytes. This scenario motivated the inception of green analytical chemistry (GAC), a growing research field with the goal of designing novel analytical methods in which the toxicity and amount of waste are minimized without affecting or even enabling superior analytical performance. This Special Issue entitled “Green Analytical Chemistry: Development of Sustainable Analytical Methods for Food and Environmental Samples” aims to encourage scientists to publish new green analytical methods as well as critical reviews in this topic. New insights in sampling, sample pretreatment, and analyte determination are welcomed. Topics to be covered in this Special Issue may include but are not limited to:

- Analytical methods that contribute to the reduction of pollution, including real-time analysis of pollutants;

- Analytical methods to avoid sample pretreatment or involving greener approaches for sample pretreatment, including safe solvents and auxiliaries;

- Miniaturization and automation, including flow analysis and microfluidics;

- Green separation techniques;

- Treatment of toxic chemicals generated by analytical methodologies.

The application of urea-based selective catalytic reduction products (i.e., Urea-SCR) provides a reduction of NOx and, therefore, minimizes pollution emissions from vehicles fueled by diesel. Such products can be easily found in the market; however, they are often susceptible to adulteration, mainly in terms of the urea content and dilution with non-mineralized water. In this study, we propose a simple, low-cost, disposable, and straightforward paper-based microfluidic device for the quality-control of Urea-SCR products for the first time by quantifying urea and water hardness simultaneously via colorimetric reactions using a small volume of sample. 4-(dimethylamino)benzaldehyde and Eriochrome T were used as colorimetric indicators for urea and water hardness determination, respectively. Each reagent (1.5 µL) was combined with 6 µL of sample for analysis, contributing to an expressive reduction of waste generation. Digital images of the µPAD were obtained, and linear relations between color intensity and urea and Ca2+ and Mg2+ concentrations in the range of 0.2 to 1.0% and 0.1 to 3.5 mmol L−1 were obtained with a correlation coefficient higher than 0.99. Recovery experiments were employed to evaluate the accuracy of the methodology, revealing suitable values between 91.5 and 115%. Brazilian Urea-SCR samples were acquired from different distributors and submitted to the proposed procedure to evaluate its applicability. The application of microfluidic paper-based devices with colorimetric reactions enables the quality control of Urea-SCR products with high accuracy, portability, low consumption of reagents, and no generation of toxic residues; thereby contributing to the green analytical chemistry field.

A portable OH radical scavenging demand analyzer that can be installed and operated on site was developed to measure water quality indicators that influence the generation of OH radicals from UV/hydrogen peroxide reactions to determine the UV dose and the hydrogen peroxide injection concentration. Rhodamine B (RhB) was used as an indicator for the continuous measurement of the OH radical scavenging demand of four samples with different water quality parameters using the rapid, easy, and real-time UV-Vis spectrophotometer method. The results demonstrated that the estimated rate constant for the RhB color decay rate resulting from direct UV photolysis was low enough to verify its suitability as a probe compound. The mean values of the OH radical scavenging demand for target water samples at different organic concentrations were 20,659 s−1 for plant N, 42,346 s−1 for plant C, 32,232 s−1 for plant Y, and 81,669 s−1 for plant B. Variations in the monitoring results for the target water treatment plants suggest that on-site OH radical scavenging demands should be considered to determine the UV dose and the hydrogen peroxide injection concentration for the UV advanced oxidation process.
