The energy demand of the world is skyrocketing due to exponential economic growth and population expansion. To meet requirement, use fossil fuels not a good decision, causing environmental pollution such as CO2 emissions. Therefore, renewable sources like biofuels can crisis especially for countries facing oil shortages Pakistan. This review describes comparative study biodiesel synthesis various edible oils, non-edible wastes waste plastic oil, biomass pyrolysis tyre in terms their content...
Up till now, despite of well-developed ornamental market, very little information is available on Petunia hybrida L. tolerance against heavy metals (HMs), which can contribute in both beautification urban dwellings, as well potential phytoremediation. Therefore, hydroponic study was conducted to check the effects Cd, Cr, Cu, Ni and Pb individually (50 100 μM) with co-application EDTA (2.5 mM) Hoagland's nutrient solution. Results indicated higher uptake above ground parts, Cu roots, further...
A photocatalytic system for decolorization of double azo reactive black 5 (RB5) dye and water disinfection E. coli was developed. Sol gel method employed the synthesis Fe-TiO2 photocatalysts were characterized using thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) coupled with energy dispersive (EDX), transmission (TEM), diffuse reflectance (DRS) Brunauer–Emmett–Teller (BET) analysis. Results showed...
Rapid industrialization and increasing population are continuously adding contaminants to our environment. Among those, heavy metals considered be one of the serious threats ecosystem due their persistent nature. Microbe assisted phytoremediation is an effective tool for metal remediation as microbes enhance availability uptake host plants or reduce it by binding them intracellularly extracellularly. An endophytic fungus, Trametes hirsuta, was isolated from Chenopodium album L. plant growing...
Waste wood biomass as precursor for manufacturing activated carbon (AC) can provide a solution to ever increasing global water quality concerns. In our current work, Melia azedarach derived phosphoric acid-treated AC (MA-AC400) was manufactured at laboratory scale. This novel MA-AC400 tested RO16 dye removal performance function of contact time, adsorbent dosage, pH, temperature and initial concentration in batch scale arrangement. characterized via scanning electron microscopy, energy...
The problem of metal-induced toxicity is proliferating with an increase in industrialization and urbanization. buildup metals results severe environmental deterioration harmful impacts on plant growth. In this study, we investigated the potential two ornamental plants, Catharanthus roseus (L.) G.Don Celosia argentea L., to tolerate accumulate Ni, Cr, Cd, Pb, Cu. These plants were grown Hoagland’s nutrient solution containing metal loads (50 µM 100 µM) alone combination a synthetic chelator,...
Abstract BACKGROUND Fe 2 O 3 /ZnO hybrid nanoadsorbent was synthesized by the coprecipitation method and characterized. The hydrodynamic size stability of were investigated in batch adsorption toxic Reactive orange (RO)16 dye at increasing concentrations. mechanism monolayer multilayer elucidated for first time together through dynamic light scattering (DLS), isotherm, kinetic thermodynamic studies. A tomato seed germination assay performed to confirm material treated water toxicity. RESULTS...
Abstract Cr(VI) adsorption was studied for abundantly available low-cost lignocellulosic adsorbents in Pakistan namely, tobacco stalks (TS), white cedar stem (WCS) and eucalyptus bark (EB). Several process variables like contact time, adsorbent dose, pH, metal concentration, particle size temperature were optimized batch mode. EB showed high of 63.66% followed by WCS 62% TS 57% at pH 2, which is higher than most the reported literature. Langmuir isotherm (R 2 = 0.999) well fitted into...
Dye effluents and their degradation products disrupt the aquatic ecosystem functioning. Corncob was used as a low-cost biosorbent for decolorization of methylene blue (MB) dye. Batch fixed-bed column adsorption were performed by varying temperature, pH, initial dye concentration, adsorbent dose, particle size, bed height, flow rate inlet respectively. High MB capacities corncob attained at pH 9, i.e. 45.86 mg g−1, 91.7%. Equilibrium data best described Langmuir II (R2 = 0.999) followed...
Phenolic compounds are toxic and ominously present in industrial effluents, which can end up water bodies, causing potential damage to living organisms. This study employed the dried biomass of freshwater green microalgae Chlorella vulgaris remove phenol 2-chlorophenol from an aqueous environment. C. was grown under different phosphorus- (P) starved conditions, treated with sulfuric acid. It observed that reducing P level enhanced lipid content by 7.8 times while decreasing protein 7.2...
T he nutrient cycle and organic matter decomposition are catalyzed by soil enzymes. In this study, enzymatic activities of catalase, dehydrogenase, alkaline phosphatase, urease studied in soils amended with compost (C), moss (M), or biochar (B) irrigated heavy metal-contaminated wastewater (HM-CW), when Nicotiana alata L. Petunia hybrida was grown pots. The irrigation HM-CW reduced the enzyme activities. However, combined used 5% M+C+B, results improved case N. P. hybrida, catalase activity...
As growth regions evolve to accommodate the increasing population, they need develop a wider variety of residential properties varying needs residents. result, new accommodation is denser which involves higher embodied water carbon and energy. This research compares construction differences in metropolitan Melbourne identify carbon, water, Representative areas 25 km2 are selected from both regions. The region has 80% built area comprised 2nd generation low-rise buildings whereas prolific...
