Bio-inspired perylene diimide coated super paramagnetic nanoparticles for the effective and efficient removal of lead(ii) from aqueous medium

Abstract

Instability in water, complexity of separation of toxic substances produced, reusability issue of reported materials used for decontamination of lead from water- these hindrances have caught the attention of modern...

Recent advances in magnetic digital microfluidic platforms

“…In their experiments, three main regions (steady transport, magnet disengagement, and particle extraction) were defined to describe the relationships between magnetic particles and droplet movement patterns) and to analyze the forces exerted by magnetic particles. Also, it has been noted that the use of superparamagnetic particles can achieve more precise control of microdroplets with less interference to the magnetic field [37][38][39].…”

“…Magnetic DMF can be used to detect hazardous chemicals such as harmful heavy metals ions. D. Sucharita et al [37] designed a bio-inspired perylene diimide coated superparamagnetic particles (having Fe 3 O 4 clusters as a magnetic beads core and dihydroxyphenylalanine as a cover) for Pb + detection and reduction. Since microporous liquid marbles have a large surface-to-volume ratio, they have a higher binding efficiency of lead ions.…”

Surface and Structural Modulation of Waste‐Derived, Boron‐Doped Carbon to Enhance its Adsorption Efficiency for Lead Removal from Wastewater

“…The nanomaterial has a remarkable adsorption capacity of 1407.5 mg/g and a Kd value of 1.14×106 mL/g. It can effectively reduce the Pb(II) concentration from 4000 to 7 ppb with 99.97% efficiency, even at a low pH level [25] . Green cobalt‐oxide nanoparticles (Co 3 O 4 NPs) synthesized using chemical co‐precipitation were used to remove Pb ions from simulated wastewater solutions.…”

[25] Green cobalt-oxide nanoparticles (Co 3 O 4 NPs) synthesized using chemical co-precipitation were used to remove Pb ions from simulated wastewater solutions. The NPs were characterized using various analytical techniques, including FTIR, Raman, SEM, UV visible, XRD, and BET.…”

Retention of perylene diimide optical properties in solid-state materials through tethering to nanodiamonds

“…Notably, chemical functionalisation of the imide nitrogen with carbon-based groups, e.g. alkyl or aryl groups, barely influences the properties of the core and thus provides a simple method of attaching the PDI to larger species, for example polymers 14,15 or nanoparticles, 16,17 whilst retaining the PDIs most interesting physicochemical features.…”
