Three-dimensional paper-based electrochemiluminescence device for simultaneous detection of Pb2+ and Hg2+ based on potential-control technique

Development of an electrochemically reduced graphene oxide modified disposable bismuth film electrode and its application for stripping analysis of heavy metals in milk.

A facile method has been developed for fabricating selective and sensitive electrochemical sensors for the detection of toxic metal ions, which invokes incorporation of palladium nanoparticles (Pd NPs) on porous activated carbons (PACs). The PACs, which were derived from waste biomass feedstock (fruit peels), possess desirable textural properties and porosities favorable for dispersion of Pd NPs (ca. 3–4 nm) on the graphitic PAC substrate. The Pd/PAC composite materials so fabricated were characterized by a variety of different techniques, such as X-ray diffraction, field-emission transmission electron microscopy, gas physisorption/chemisorption, thermogravimetric analysis, and Raman, Fourier-transform infrared, and X-ray photon spectroscopies. The Pd/PAC-modified glassy carbon electrodes (GCEs) were exploited as electrochemical sensors for the detection of toxic heavy metal ions, viz., Cd2+, Pb2+, Cu2+, and Hg2+, which showed superior performances for both individual as well as simultaneous detections.

Currently, no literature extensively reviews the availability and the potential of Moringa oleifera parts as a non-competitive low-cost value-added renewable source for biosorbents, particularly for bioremediation and water purification usage in poverty threatened areas of developing nations. The present review article discusses the potential of this plant as a substitute to expensive and synthetic technologies for the removal of toxic metals from contaminated aqueous systems while critically evaluating research results presented in rather too few articles that exist. The main biosorption processes linked to heavy metal sequestration is assessed. The coagulation properties of Moringa oleifera for organic contaminant removal are analyzed and linked to their metal biosorption mechanism. The removal of heavy metals and its potential accumulation in granular medium of M. oleifera are also discussed. Current advanced models used in bioadsorbent studies are presented as a powerful tool for understanding multiple interactions occurring in aqueous systems during the removal of contaminants using M. oleifera. On account of its enormous pharmacological significance, water coagulation properties and potential for heavy metal sequestration, M. oleifera, which can be easily be domesticated in areas where they lack versatility in growth such as Southern Africa, can be a good candidate as a biosorbent in bioremediation of hazardous aqueous systems (contaminated environments or effluents) and water purification.
