Abstract Polypyrrole (Ppy) and Ppy/Ni(OH) 2 ‐NiO nanocomposite are prepared through the in situ polymerization oxidation reaction (on glass), which composite is formed of NiSO 4 . The materials were characterized to reveal their morphology, chemical structure, optical properties. Ppy have average particle sizes 160 250 nm, respectively. Moreover, bandgap values 1.70 1.44 eV, Through composite, polymer acts as a shell (40 nm), while Ni(OH) core. Analysis illustrates that crystalline nature...
This study is very promising for providing a renewable enrgy (H2 gas fuel) under the elctrochemical splitting of wastwater (sewage water). has double benefits: hydrogen generation and contaminations removel. carried out on sewage water, third stage treated, from Beni-Suef city, Egypt. Antimony tin oxide (ATO)/polyaniline (PANI)/PbI2 photoelectrode prepared through in situ oxidative polymerization PANI ATO, then used as an assistant PbI2 deposition using ionic adsorption method. The chemical...
Biomass is an excellent source of green energy with numerous benefits such as abundant availability, net carbon zero, and renewable nature. However, the conventional methods biomass combustion are polluting poor efficiency processes. gasification overcomes these challenges provides a sustainable method for supply greener fuel in form producer gas. The gas can be employed gaseous compression ignition engines dual‐fuel systems. process complex well nonlinear that highly dependent on ambient...
The Instrumental Neutron Activation Analysis (INAA) technique was used to analyse 10 cigarette brands sold in the Egyptian market. concentrations of trace and major constituents were measured better understand hazardous effects smoking tobacco. samples irradiated at core Second Research Reactor ET-RR-2, induced activities counted by <gamma>-ray spectrometry using an efficiency-calibrated High Purity Germanium (HPGe) detector. NAA k0-standardization method determine 14 elements (Ba, Br, Ca,...
Conventional methods for removing nitrate and nitrite anions from wastewater include reverse osmosis, ion exchange, combined membrane bioreactor/powdered activated carbon adsorption, the biofilm-electrode reactor (BER) BER/adsorption process [7].Most of these suffer some drawback, such as high capital or operational cost disposal resulting sludge [7,8].Recently, numerous low-cost alternative adsorbents have been examined removal [9-13].

Polyacrylamide PAAm used as a for the polymerization of MA in an aqueous solution using gamma rays initiator. The effects on capacity P(AAm-MA), such concentration maleic acid and amount polymer, were investigated. has been utilized adsorbent removal Co(II) Ni(II) ions from solution. time equilibrium, pH, temperatures, dosage have studied. equilibrium data analyzed Langmuir Freundlich isotherm...
Abstract Poly (acrylamide-acrylic acid-dimethylaminoethylmethacrylate), p(AM-AA-DMAEM) and Poly(acrylamide-acrylic acid)-ethylenediaminetetracetic acid disodium, p(AM-AA)-EDTANa2 were prepared by gamma radiation-induced template polymerization technique used for the separation of Ga (III) from Cu (II), Ni Zn (II) in aqueous media. The effect pH contact time on process was studied. optimum value is 3–3.5. result shows that first extracted while Zn(II) are slightly at this value. recovery...
Attention over greenhouse gas emissions has driven interest in cleaner energy sources including alternative fuels. Waste-derived biogas, which is produced by the anaerobic digestion of organic waste such as municipal solid waste, agricultural residues, and wastewater sludge, an intriguing biofuel source due to its abundant availability promise lowering emissions. We investigate potential waste-derived biogas fuel for a dual-fuel engine that also uses diesel secondary this study. suggest...

A fast and sensitive on-line procedure for the determination of zinc in water biological samples was developed. Zinc preconcentrated a mini-column packed with polyurethane foam (PUF) chemically modified zincon via -N=N- bonding. The optimal conditions preconcentration were pH 8.5 sample flow rate 4.0 mL min(-1). Quantitative desorption Zn(II) obtained by 0.1 mol L(-1) hydrochloric acid subsequent spectrophotmetric using 4-(2-pyridylazo)-resorcinol at 498 nm. detection limit found to be 3.0...
활성탄소를 가지고 수용액으로부터 전이금속이온을 제거 능력에 대해 시험했다. 탄소의 물리적, 화학적 그리고 액체-상 흡착 특징은 다음의 기준 절차로 수행하였다. Ni(II), Cu(II) Fe(III)이온의 연구는 흡착물질의 양, 금속이온 용액의 pH, 배치 모드에서 시간을 다양하게 하여 시도되었다. 평균 데이터는 Freundlich와 Langmuir로 맞춰졌고 등온 상수는 계산되었다. 다른 세가지 금속 이온의 시간은 결정되었다. pH는 흡착에 있어서 중요한 역할을 하는 것을 발견했다. 이 과정은 흡열반응이었고, 열역학 인자는 이온교환 메커니즘이 작용되는 나타내고 있다. An activated carbon was tested for its ability to remove transition metal ions from aqueous solutions. Physical, chemical and liquid-phase adsorption characterizations of the...
