The aim of the present study was to utilise pristine and magnetite-sucrose functionalized Nigella Sativa seeds as adsorbents for uptake chromium(VI) lead(II) ions from synthetic wastewater. Prestine were labelled (PNS) (FNS). PNS FNS composites characterized by Fourier-transform infrared spectroscopy (FTIR) X-ray powder diffraction (XRD). FTIR analysis both revealed presence vibrations assigned 1749 1739 cm -1 (-C=O) ketonic group adsorbents. amide (-NH) peak observed at 1533 1527 on...
Toxins in water, such as metal ions and dyes, have become a global challenge to humanity by causing several serious illnesses. Removal of these toxins from water is needed for human health environmental concerns. This work investigated the use hemp seeds an environmentally friendly adsorbent applications treatment. Pristine (PHSs) were carbonized at 500 700 °C obtain carbon-based (CHS-500 CHS-700 removal cadmium methylene blue. The morphological functional groups adsorbents pristine...
Ubiquitous toxic metal ions and pathogenic microbes in contaminated water affects the lives of millions people globally. The synthesis multifunction composites that can uptake ion from simultaneously inhibit growth is a novel concept. This study developed composite substances fennel seeds impregnated with binary nanoparticles CuO-ZnO. These were used to remove Cr(VI) Escherichia coli Staphylococcus aureus. SEM analysis surface starting material showed various sizes shapes pores. In contrast,...
Abstract In this work silver nanoparticles (AgNPs) have been prepared from nitrate (AgNO 3 ) precursor using a green synthesis method at room temperature. Starch with its abundance of hydroxyl groups and biocompatibility was used as capping reducing agent. The formation AgNPs confirmed by absorption spectroscopy the surface plasmon resonance peak 400 nm. sharp reflection (111), (200), (220) (311) observed powder X-ray diffraction (XRD), which indicated presence cubic phase AgNPs....
The whole world is faced with a huge challenge of the shortage clean water due to industrialization and intimidation climate change. Poor quality distresses many areas human’s well-being. Although there are existing technologies for treatments, these methods utilize toxic substances which create more problems into environment. preparation bis (N-benzyl-salicydenaminato)zinc (II) complex synthesis zinc oxide nanoparticles via thermal decomposition together fabrication ZnO-chitosan...
