Background and Objectives: Increasing waste tiers production has made the recycling of this solid waste a critical issue in the world. On the other hand, it seems contamination of groundwater to the petroleum pollutant like gasoline is a great threat to the health of societies in developing countries. The main objective of this study was gasoline removal from aquatic environment by waste tire d...
Lithium-oxygen cells have attracted extensive interests due to their high theoretical energy densities. The main challenges are the low round-trip efficiency and cycling instability over long time. However, even in the state-of-the-art lithium-oxygen cells the charge potentials are as high as 3.5 V that are higher by 0.70 V than the discharge potentials. Here we report a reaction mechanism at a...
Present review article describes main causes of chronic kidney disease a major health problem public health problem round the globe. Disease has multiple etiologies related to sequential pathophysiological stages. It has major concern with chronic changes in renal structure and that severely alter glomerular filtration rate in patients. This article explains CKD biomarkers in brief i.e., serum ...
In this study, ZnO nanoparticles were loaded on activated carbon prepared from almond shell (ZnO-NP-AC). Then, this novel material applied as an efficient adsorbent for the ultrasonic assisted simultaneous removal of Basic Blue 41(BB41) and Basic Red 46 (BR46) in binary solution. The efficiency of proposed activated carbon was enhanced by acid treatment and subsequent modification by physical ...
Background & Aims of the Study: The presence of antibiotics in the environment, especially in aquatic environments is a major concern for health and the environment. The advanced oxidation process due to the ease of use, economical advantages and high performance have attracted a lot of attention. The purpose of this study was Evaluating of the photocatalytic role of zinc oxide on s...
Background and Aim: Availability and low cost of date stones make them useful as raw material in the preparation of activated carbon. Cyanide, because of its toxicity for humans and aquatic organisms, is one of the most important health problems. The aim of the present study was to evaluate cyanide removal from aqueous solutions and determine influencing parameters in its adsorption into activa...
Background: One of the possible carcinogenic substances found in foods is Acrylamide (AA). This study aims to combine and innovate sea grapes (Caulerpa racemosa) extract with activated carbon into paper towels that can absorb AA levels in fried foods. Methods: The paper towel was created with composition of activated carbon: sea grapes extract: paper pulp using following formula: F0=0:0:100; F...
This study investigated the mechanism by which activated carbon removes trichloramine, a byproduct of water treatment that has a strongly offensive chlorinous odor. A stoichiometrical mass balance for ¹⁵N before and after activated carbon treatment of laboratory-prepared ¹⁵N-labeled trichloramine solutions clearly revealed that the mechanism of trichloramine removal with activated carbon was no...
The purpose of this study was to the effect percentage addition conductivity material in phosphorylation starch modify GCE (glassy carbon electrode) for detection Cr(VI). In study, technique used is DPV (Differential Pulse Voltammetry). activated and Fe3O4 nanoparticles. method an optimization determination performance obtained sensor. optimum materials, both nanoparticles, matrix 5%. form amor...
In the present study, carbon black activated by CO2 gas was examined through XRD analysis, especially with regard to changes in its structural parameters. Based on results, activation process thoroughly analyzed. The controlled isothermally activating inside a reaction tube which flowed. With this approach, degree of varied as desired. At an early stage process, amorphous fraction surface prefe...
