“…CE is one of the widely used adsorbent materials due to its easy accessibility, nontoxic nature, biodegradability, and potential for surface functionalization. Furthermore, many attempts have been made to functionalize CE − but rarely tested for the effective removal of multiple pollutants. Here, we investigated the use of PEI-modified CE obtained from the banana stem to remove both heavy metal ions and dyes from water.…”

Efficient removal of organic and inorganic pollutants is a challenge owing to the involvement of different physicochemical properties. Herein, we discuss a novel approach for successive adsorption of oppositely charged multiple compounds [acid fuchsin (AF), Cu(II), perylene tetracarboxylate (PTC) anions, and Zn(II) ions] from water using chemically modified cellulose fibers (PEI/CE). The changes in net surface charges of the adsorbent accompanied by the successive adsorption of oppositely charged compounds from water are utilized as a concept for adsorption of multiple pollutants on the same adsorbent. The PEI/CE adsorbent was separated via simple filtration after each adsorption experiment and used directly for further successive adsorption without any drying or surface treatments. Compared to most of the reported adsorbents, PEI/CE fibers showed excellent adsorption capacities of 562, 552, 216, and 157 mg/g for AF, Cu(II) ions, PTC dye, and Zn(II) ions, respectively. Analysis of the data from kinetic and isotherm studies revealed the best fit to the pseudo-second-order and Langmuir isotherm model for all adsorbates. Furthermore, data from the zeta potential measurements and elemental analysis helped to establish the mechanism of the adsorption process. Such concepts are viable for the removal of known pollutants from multiple industrial effluents. A series of such simple, renewable adsorbents and successive adsorption processes could be developed as a new platform for effective removal of several pollutants from wastewater effluents.

“…All these methods are reliable for the qualitative and quantitative determination of Cd(II), but they are time-consuming, expensive, and not suitable for on-site determination. The calorimetric approach proposed by [ 34 – 37 ] is free from these problems but not capable of differentiating between two nearby ranges and the LOD is also on the higher side. The electrochemical sensor described in [ 38 ] is a good approach, but it also requires a lab instrument for measurement.…”

This paper proposes the selective and ultrasensitive detection of Cd(II) ions using a cysteamine-functionalized microcantilever-based sensor with cross-linked ᴅʟ-glyceraldehyde (DL-GC). The detection time for various laboratory-based techniques is generally 12–24 hours. The experiments were performed to create self-assembled monolayers (SAMs) of cysteamine cross-linked with ᴅʟ-glyceraldehyde on the microcantilever surface to selectively capture the targeted Cd(II). The proposed portable microfluidic platform is able to achieve the detection in 20–23 min with a limit of detection (LOD) of 0.56 ng (2.78 pM), which perfectly describes its excellent performance over other reported techniques. Many researchers used nanoparticle-based sensors for the detection of heavy metal ions, but daily increasing usage and commercialization of nanoparticles are rapidly expanding their deleterious effect on human health and the environment. The proposed technique uses a blend of thin-film and microcantilever (micro-electromechanical systems) technology, which mitigate the disadvantages of the nanoparticle approaches, for the selective detection of Cd(II) with a LOD below the WHO limit of 3 μg/L.

In this paper, we proposed the selective and ultrasensitive detection of Cadmium ions using a Cysteamine functionalized microcantilever-based sensor with cross-linked DL-glyceraldehyde. The detection time for various laboratory-based techniques is generally 12-24 hours. The experiments performed to create the SAMs of Cysteamine (Cys) cross-linked with DL-glyceraldehyde on the Microcantilever surface to selectivity capture the targeted Cd2+ Ions. The proposed portable microfluidic platform able to achieve the detection in 20-23 minutes and having a Limit of Detection (LOD) of 0.56 ng (2.78 pM), which perfectly describes its excellent performance over other reported techniques. Many researchers used Nanoparticles (NPs)-Based sensors for Heavy metal ions detection, but day by day, increasing usage and commercialization of Nanoparticles are rapidly expanding their deleterious effect on human health and the environment. The proposed technique uses the blend of thin-film and microcantilever (MEMS)-technology to overdrive the disadvantages of the Nanoparticles-approaches for selective Cd2+ ions detection and having LOD less than WHO limit of 3 µg/L. The fabricated sensor can achieve the limits efficiently well below the standards set by the WHO and helpful for the early detection of HMIs polluted source.
