The removal of anthracene from vehicle-wash wastewater (VWW) was investigated using adsorption employing biochar (EWB) generated eucalyptus wood waste. EWB characterized analytical techniques such as surface area analysis (SAA), scanning electron microscopy (SEM), and fourier transform infrared (FT-IR). study determined that the most effective conditions to achieve maximum (98.40%) were follows: an initial concentration 40 ppm, a contact time 60 min, pH level 5, temperature 50 °C, adsorbent...
Smart cities, a new kind of urbanization, offer means achieving the condition in which environmental conservation and economic growth are mutually beneficial. As result, it is important to think about whether how development smart cities might support high-quality urban economies. Based on panel data 163 prefecture-level China from 2009-2018, green total factor productivity (GTFP) each city measured using SBM-GML model, appropriate spatial econometric model screened by various types tests....
This study investigates the removal of fluoranthene (Flu) from vehicle-wash wastewater (VWW) using biochar (EWB) derived eucalyptus wood waste. Analytical techniques such as surface area analysis (SAA), scanning electron microscopy (SEM), and fourier transform infrared spectroscopy (FT-IR) were employed to characterize EWB. Optimal conditions for Flu adsorption (98.80%) determined 40 ppm initial concentration, 60 minutes contact time, pH 5, 60°C, 0.4 g adsorbent dosage. The process was...
Dehydrogenation (—H2) of propan-2-ol and butan-2-ol to the corresponding ketones and/or their dehydration (—H2O) alkenes have been compared over high purity powdered oxides fourth row transition metals. Activities commercially available Al2O3, SiO2 TiO2 catalyst supports were also determined. Quartz microcatalytic reactions with gas chromatographic analysis used in both continuous-flow pulsed-reactant model study dependence sample activity processes upon state oxidation–reduction surface,...
Lead (Pb) is a toxic environmental contaminant, which enters water bodies from natural and anthropogenic activities. The present study investigates the Pb concentration in groundwater sources evaluates their potential health risks Palosai area, Peshawar, Khyber Pakhtunkhwa, Pakistan. Groundwater samples were collected different area where human blood dependent residents. was analyzed using an atomic absorption spectrophotometer compared with permissible limits set by Pakistan Environmental...
The present study is an effort to document bio-geographical distribution for Zygoptera of Pakistan. Damselflies were collected throughout the country and territory Azad Jammu Kashmir during 2004-2009. A total 2692 specimens yielding 9 families, 21 genera, 48 species subspecies. Three these species, Libellago lineata (Burmeister), Elattoneura atkinsoni (Selys), souteri (Fraser), are recorded first time from Distribution, habitats, previous records, zoogeographic affiliation all taxa...
The synthesis of graphene oxide (GO) from fish scales and its application for the adsorptive removal organic contaminants refinery wastewater is described in this article.
Potentially poisonous elements (PPEs) water pollution has become one of the key issues in field treatment. In recent years, it threatened ecosystems as well human health. This study aims to remove PPEs such chromium (Cr6+), copper (Cu2+), lead (Pb2+), and Zinc (Zn2+) from both vehicle wash wastewater aqueous solutions through batch experiments utilising carbonaceous adsorbents. Carbonaceous adsorbents were prepared waste polyethylene terephthalate (wPET) polystyrene (wPS) by carbonisation...
In this study, waste polyethylene terephthalate (wPET) and polystyrene (wPS) was converted into activated char (AC) utilized for the removal of polycyclic aromatic hydrocarbons (PAHs) from vehicle-wash wastewater (VWW).AC prepared by carbonization in nitrogen atmosphere at high temperature followed chemical activation with 1 M KOH HCl.The AC investigated surface area analyser, Fourier-transform infrared spectroscopy as well scanning electron microscopy.The PAHs VWW through examined batch...
In recent years, the contamination of water by potentially poisonous elements (PPEs) has got one major issues that undermine ecological systems as well human health.The current examination is aimed at eliminating PPEs like zinc (Zn 2+ ), chromium (Cr 6+ lead (Pb and copper (Cu ) from aqueous solutions vehicle-wash wastewater (VWW) utilizing biochar/bentonite/ waste polyethylene terephthalate (wPET/C/Bt) biochar/bentonite/waste polystyrene (wPS/C/ Bt) an adsorbents.The adsorbents were...
Abstract The trophic magnification slope (TMS) of mercury has been reported from >130 aquatic systems in the world. However, data Asia-Pacific region is quite lacking despite need for estimation Hg exposure via fish consumption many those regions Here we provide TMS values three marine Pacific rim, Oregon coast, USA, Sanriku Japan, and Jakarta Bay, Indonesia. A decreasing trend temperate to tropical was found this study.
Abstract Marine mussels permanently adhere to various surfaces via catechol (1,2‐dihydroxybenzene) functional groups. Such biofouling causes adverse effects, including the corrosion and dragging of a marine vessel. By using density theory, we show an electrical stimulus detach molecule that strongly adhered silica surface. A moderate electric field significantly decreases binding energy dry or wet
