“…Given that removing heavy metal ions by adsorption significantly depends on the pH of the solution, a set of experiments was planned at different pH values between 2.0 and 8.0. However, precipitation occurred with a sudden decrease in the pH of the solution.…”

Pollution control has become increasingly important in recent years. Heavy metal ions, proteins, and dyes are frequently found in wastewater because of their extensive industrial applications. In this study, pH, temperature, and magnetic triple‐responsive poly(N‐isopropylacrylamide‐co‐methacrylic acid) porous microspheres doped with magnetite nanoparticles as a new type of smart adsorbents are used to remove the aforementioned pollutants. The pH‐ and temperature‐responsiveness of these microspheres realizes tunable adsorption toward Cu(II). Simultaneously, the microspheres exhibit good adsorption capability to lysozyme and basic fuchsine. Microsphere‐adsorbing pollutants are easlily separated from wastewater by applying an external magnetic field to reuse the microspheres.

“…12 and gas chromatography coupled with mass spectrometry and spectrophotometry 13 ), there are few electroanalytical techniques reported for the determination of herbicide 2,4-D using traditional carbon electrodes and mercury electrodes. 14,15,16 The 2,4-D and its by-product reveal slow electron transfer, suggesting that the redox method is electrochemically irreversible. The electroinactivity of 2,4-D has been reported and the determination of this compound through electrochemical strategies is not straightforward at present.…”

In this work, the development of an electrochemical method for the determination of 2,4-dichlorophenoxy acetic acid (2,4-D) (indirectly by converting to its electroactive nitrated form) using a modified screen-printed carbon electrode with bismuth film is reported. The electrode modification has been done by a single potential step electrodeposition of bismuth film on screen-printed carbon electrodes. Under the optimized conditions, the nitrated 2,4-D showed a dynamic linear concentration range in pH 11 buffer from 11.1 to 74.3 µM with regression coefficient (R) of 0.9988. The limits of detection and quantification were 3.15 µM and 10.5 µM, respectively. The proposed method offered higher sensitivity compared to bare screen-printed carbon electrodes. The modified electrode showed good reproducibility, repeatability, stability and recovery for the analysis of 2,4-D. The developed method was used for electroanalysis of 2,4-D in soil and water samples collected from Sito Kebele, Dedo district Jimma zone.

“…Metallo-porphyrins (MPs) is a kind of important 18π-conjugated organic molecules and have been extensively employed to mimic the active sites of enzymes such as hemoglobin, myoglobin, cytochrome and nitric oxide reductase in electrochemical study 5~8 . Thus, the preparation and application of suitable designed electrode surfaces of porphyrins have attracted considerable attention during the last several decades 6,9 . Since it was introduced by Sagiv, self-assembly monolayer (SAM) of porphyrin thiolates on gold has been used as an efficient method to prepare stable and oriented electrode surfaces of porphyrins with a controllable thickness and desirable function 10,11 .…”

Disulphide derivatised mesoporphyrin (DSDMP) and its cobalt complex Co(II)DSDMP were conveniently synthesized and successfully immobilized onto gold surface by monolayer self-assembly of disulfide. The modified electrode was characterized by Infrared Spectrometer (IR) and X-ray photoelectron spectroscopy (XPS) and confirmed electrochemically by cyclic voltammogram (CV) and differential pulse voltammogram (DPV). The characterization results supported the stable formation of Co(II)DSDMP monolayer with a surface coverage of 1.48×10-10 mol/cm-2 .
