“…is combination led to a technique that preconcentrates and separates target compounds from matrix interferents at the same time. is technique does not need organic solvent if we use TD or only a small volume of organic solvent if we use backextracting, and it allows ultra-trace detection of a wide range of compounds in a liquid medium [66]. Coupling PAL system with design specific thermal units that provide both heating and cooling within the same block (− 80 °C to +250 °C with a ±0.1 °C), commercialized by Mècour (Grooveland, US), ICECLES can be completely automated.…”

The solid-phase microextraction (SPME), invented by Pawliszyn in 1989, today has a renewed and growing use and interest in the scientific community with fourteen techniques currently available on the market. The miniaturization of traditional sample preparation devices fulfills the new request of an environmental friendly analytical chemistry. The recent upswing of these solid-phase microextraction technologies has brought new availability and range of robotic automation. The microextraction solutions propose today on the market can cover a wide variety of analytical fields and applications. This review reports on the state-of-the-art innovative solid-phase microextraction techniques, especially those used for chromatographic separation and mass-spectrometric detection, given the recent improvements in availability and range of automation techniques. The progressively implemented solid-phase microextraction techniques and related automated commercially available devices are classified and described to offer a valuable tool to summarize their potential combinations to face all the laboratories requirements in terms of analytical applications, robustness, sensitivity, and throughput.

“…176 Later on, novel coating materials with improved analytical features were introduced, 177,178 although not all of them are commercially available. 174 Alternatively, novel working modes for simultaneous extraction of analytes with different polarity, such as multishot, 179 sequential extraction, 180 ice concentration linked with extractive stirrer (ICECLES), 181,182 or solvent-assisted SBSE; 183 and new SBSE configurations, such as dual-solvent SBSE, in which the organic phase was confined to a pair of hollow-fiber membranes fixed on a stir bar, 184 has been investigated. The feasibility of SBSE with in-situ and in-tube derivatización, as well as in-situ deconjugation has also been demonstrated and discussed in different recent review articles.…”

Challenges in Green Analytical Chemistry

Sample preparation is still identified as the bottle-neck of many modern analytical procedures due to the time-demanding nature of many of the treatment protocols in use. Sample treatment is also considered responsible for a large part of the analytical inaccuracy of the analytical methodologies because of the highly manipulative nature of most of these treatments. It is also one of the main limitations when trying to develop Green Analytical procedures due to the large amounts of reagents and energy consumption typically associated to most of the conventional sample preparation procedures. However, the efforts carried out during the last decades in this active research field are starting to revert the situation. Today, a plethora of miniaturized techniques are commercialized for the treatments of liquid (or dissolved) samples. When combined with an appropriated state-of-the-art separation-plus-detection technique, accurate analyte determination is possible even if only a very small amount of sample (i.e., few mg or mL) is used for the analysis. More importantly, many of the these techniques allow sample preparation to be completed in a short time with minimum reagents and energy consumption, and with a significant reduction of the wastes generated. In recent years, initial limitations detected in some of these miniaturized solvent-based techniques are starting to be circumvented by the incorporation of new non-toxic extraction media as extractants. Similarly, sorbent-based techniques have benefited from advances in the field of engineered materials and nanotechnology by incorporation of novel sorbents with tuned physic-chemical properties for enhanced extraction efficiency and selectivity.Using the analysis of trace organic components in food and environmental matrices as case study, this book chapter reviews current state-of-the-art in the field of sample preparation, highlighting recent advances approaching the principles of Green Analytical Chemistry.

“…Various procedures have been reported as effective methods for pollutants’ removal from wastewater such as reverse osmosis, distillation, ion-exchange, coagulation–flocculation, filtration, extraction and adsorption by nanoscale materials [ 5 , 6 , 7 ]. Recently, newly designed cost-effective, economic, nontoxic and productive nanoscale materials have been gained attention in various scientific areas such as the water treatment, drug delivery and solar energy conversion fields.…”

In this work, an efficient nanocatalyst was developed based on nanoadsorbent beads. Herein, carboxymethyl cellulose–copper oxide-cobalt oxide nanocomposite beads (CMC/CuO-Co2O3) crosslinked by using AlCl3 were successfully prepared. The beads were then coated with chitosan (Cs), Cs@CMC/CuO-Co2O3. The prepared beads, CMC/CuO-Co2O3 and Cs@CMC/CuO-Co2O3, were utilized as adsorbents for heavy metal ions (Ni, Fe, Ag and Zn). By using CMC/CuO-Co2O3 and Cs@CMC/CuO-Co2O3, the distribution coefficients (Kd) for Ni, Fe, Ag and Zn were (41.166 and 6173.6 mLg−1), (136.3 and 1500 mLg−1), (20,739.1 and 1941.1 mLg−1) and (86.9 and 2333.3 mLg−1), respectively. Thus, Ni was highly adsorbed by Cs@CMC/CuO-Co2O3 beads. The metal ion adsorbed on the beads were converted into nanoparticles by treating with reducing agent (NaBH4) and named Ni/Cs@CMC/CuO-Co2O3. Further, the prepared nanoparticles-decorated beads (Ni/Cs@CMC/CuO-Co2O3) were utilized as nanocatalysts for the reduction of organic and inorganic pollutants (4-nitophenol, MO, EY dyes and potassium ferricyanide K3[Fe(CN)6]) in the presence of NaBH4. Among all catalysts, Ni/Cs@CMC/CuO-Co2O3 had the highest catalytic activity toward MO, EY and K3[Fe(CN)6], removing up to 98% in 2.0 min, 90 % in 6.0 min and 91% in 6.0 min, respectively. The reduction rate constants of MO, EY, 4-NP and K3[Fe(CN)6] were 1.06 × 10−1, 4.58 × 10−3, 4.26 × 10−3 and 5.1 × 10−3 s−1, respectively. Additionally, the catalytic activity of the Ni/Cs@CMC/CuO-Co2O3 beads was effectively optimized. The stability and recyclability of the beads were tested up to five times for the catalytic reduction of MO, EY and K3[Fe(CN)6]. It was confirmed that the designed nanocomposite beads are ecofriendly and efficient with high strength and stability as catalysts for the reduction of organic and inorganic pollutants.
