We present a one-step, solid-state synthesis of Al2NiCoO5 nanoflakes (ANC) modified glassy carbon electrode (GCE) for ultra-selective and trace level simultaneous detection HMIs like copper (Cu2+), mercury (Hg2+), cadmium (Cd2+), lead (Pb2+) ions in aqua simulated blood serum samples. ANC/GCE sensor exhibits low limit (LOD = 3S/m) 0.00154 ppb, 0.00232 0.00261 ppb 0.00114 towards Pb2+, Hg2+ Cu2+...

Heavy metals, such as lead ions, are regarded the main environmental contaminants and have a negative impact on human bodies, making detection technologies of ions critical. However, most existing methods suffer from time consumption, complicated sample pretreatment, expensive equipment, which hinder their broad use in real-time detection. Herein, we show new fluorescence sensor for detecting d...

Water is not only a valuable resource that needed to sustain life, but also an essential ingredient in many engineering processes, which unavoidably leads large volumes of water being contaminated. To achieve safe discharge and recover “pollutants”, better performing sorbents are rapidly efficiently decontaminate while generating minimal secondary wastes. Bio-sorbents derived from pomelo peel w...

Mesoporous silica materials (MSMs) of the MCM-41 type were rapidly synthesized by microwave heating using silica fume as silica source and evaluated as adsorbents for the removal of Cu2+, Pb2+, and Cd2+ from aqueous solutions. The effects of microwave heating times on the pore structure of the resulting MSMs were investigated as well as the effects of different acids which were employed to adju...

Co-precipitation procedure was applied in order to obtain different kinds of magnetic nanoadsobents for the removal of Pb(II) and Cu(II) toxic metal ions from wastewater samples. Prepared nanoadsorbents were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffractometer (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The average sizes of t...

Traditional freshwater sources have been over-abstracted in the worldwide crisis of water scarcity. Effluents extremely high amounts Zn2+ and Pb2+, according to an investigation wastewater samples taken from several industrial zones. However, these heavy metals are among most harmful both humans wildlife that currently known. Streptomyces sp. is utilized this study as a biosorbent biosorb Pb2+ ...

Activated carbon is a material that has various environmental applications, such as the adsorption of metallic lead ions (Pb2+). It can be obtained from different plant species. In this research, seed Persea americana (Avocado- HASS variety) was local markets in city Cartagena to used removal Pb2+ wastewater fishing industry. To obtain activated carbon, carbonized Terrigeno-brand clay oven, Mod...

A PVC membrane electrode for lead ions based on phenyl disulfide as the membrane carrier was developed. The electrode exhibits a good Nernstian slope of 29.3 +/- 0.7 mV/decade and a linear range of 2.0 x 10(-6)-1.0 x 10(-2) M for Pb(NO3)2. The limit of detection is 1.2 x 10(-6) M. It has a response time of 45 s and can be used for at least fifty days without any divergence in potential. The pro...

Heavy metal contamination is one of the major concerns to human health because these substances are toxic and retained by the ecological system. Therefore, in recent years, there has been a pressing need for fast and reliable methods for the analysis of heavy metal ions in environmental and biological samples. Quantum dots (QDs) have facilitated the development of sensitive sensors over the pas...
