Abstract Limestone mining waste and its derived CaO were checked as an adsorbents of pb 2+ , Cu Cd ions from water solution. The characterization calcined limestone was studied by using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), Scanning Electron Microscope (SEM), Surface area measurements (BET). optimum conditions sorbent dosage, pH, initial concentration, contact time factors investigated for pristine absorbents. results...
Abstract Background Despite being necessary, copper is a toxic heavy metal that, at high concentrations, harms the life system. The parameters that affect bioreduction and biosorption of are highly copper-resistant bacteria. Results In this work, ability bacterial biomass, isolated from black shale, Wadi Nakheil, Red Sea, Egypt, for Cu 2+ attachment, was investigated. Two resistance Bacillus species were isolated; pumilus OQ931870 subtilis OQ931871. most tolerant isolate to B. . Different...
Ecofriendly chitosan/Al-MCM-48 (CH/Al-MCM) was synthesized from natural microcline and assessed as a potential adsorbent of As (V) ions with enhanced capacity. The adsorption properties CH/Al-MCM were in comparison Al-MCM-41 single phase. studied exhibits 178.6 mg/g capacity which is higher than (124 mg/g). illustrated based on the pseudo-first-order kinetic, Langmuir isotherm, monolayer model one energy site. Based recognized steric parameters, displays significant enhancement active sites...
Energy production is one of the most crucial issues presently attracting global attention. In this work, a CuMOF@Faujasite nanocomposite was synthesized and utilized as novel efficient catalyst for hydrogen production. The produced composite first characterized using X‐ray diffraction (XRD), Fourier‐ transform infrared (FT‐IR), thermogravimetric analysis (TGA), differential scanning calorimetry. Surface properties were analyzed via nitrogen adsorption–desorption isotherms. All...
The excess amount of lead (Pb<sup>+2</sup>) and cadmium (Cd<sup>+2</sup>) in the drinking water system to affect immunity kidney failure problems. To overcome such troubles by developing well-crystalline faujasite minerals that are synthesized from claystone hydrothermal process may be current trend For effective adsorption these cations. active functional group, thermal nature, crystallinity surface, texture properties, porous surface nature were investigated using X-ray diffraction,...
Natural aragonite was used as a support for different percentages (5%, 10% and 20%) of nano-Ni which obtained from nickel nitrate reduced by hydrazine hydrate. It demonstrated that the 20% catalyst has higher activity compared to other reduction p-nitrophenol p-aminophenol. The process performed in alkaline medium (NaOH) using hydrate source hydrogen. catalysts were characterised XRD, SEM, FT-IR XRF. In order discuss kinetics process, effect load concentration on initial rate studied. value...
