Efficiency of Food Waste Activated Carbon in Treating Biodiesel Plant Effluent: Impact on Process Conditions and NaOH Recovery
Water and Wastewater Treatment
In work illustrated, the mixed food reject was carbonized and further activated with zinc chloride for biodiesel washwater treatment experiments. Biodiesel washwater is one of the significant side streams generated during biodiesel production from waste cooking oil. The food waste activated carbon...

The effect of temperature on the U-232 and Am-241 adsorption by PN6 microplastics in aqueous solutions.
Microplastics in the marine environment
The effect of temperature on the adsorption of U-232 and Am-241 by PN6 has been investigated in laboratory and environmental water samples (e.g. seawater and waste water) in the picomolar concentration range. Generally, increasing temperature favors radionuclide adsorption, indicating that...

Vigna stipulacea mediated Fe nanoparticles synthesis: A greener approach for sequestration of Pb2+ from aqueous environment
Water and Wastewater Treatment
The greener approach offers a viable, sustainable and eco-friendly way to synthesize nanoparticles. This study used the seed extract of Vigna stipulacea (VS) as a bioreducing agent to synthesize iron nanoparticles (VS-Fe). The VS seed extract contains polyphenols and lignin content that acted as a...

Trace Metals Pollution in Ambient Air of Urban and Rural Coastal Environments
Environmental data analysis and modelling
Air pollution in coastal areas will have a different pattern from mountainous areas due to different wind patterns during the day and night. The city of Semarang, as a representation of urban areas, and Jepara Regency, as a representation of the rural regions, were chosen for this sampling. 24-h...

Influence of Utilizing Prosopis Juliflora Ash as Cement on Mechanical Properties of Cement Mortar and Concrete
Ecology, environmental change and management
The infrastructure of the country heavily depends on the construction material concrete. The primary ingredient in conventional concrete is cement, fly ash, or another cementitious substance. The need to explore alternative sources is driven by the challenges posed by global environmental warming...

Diatom records in sediments for eutrophication process of Lake Xian'nv, China since the mid-20th century
Ecological effects of Environmental change
To well understand the eutrophication process for inland lakes where more lands had been used for agriculture and industry without adequate environmental protections, 9 surface sediments and 1 core sediment in Lake Xian’nv which was located in the middle of Jiangxi Province were chosen. Combined...

Spatiotemporal variability of heavy metals concentration in an industrialized estuarine-bay ecosystem in Northern Persian Gulf
Ecological effects of Environmental change
This study aimed to evaluate the pollution level of Ni, Pb, Cd, V, and Hg in the sediments of Musa Estuary and its four main tributaries namely Majidieh, Zangi, Semaili, and Merimos (collectively known as Mahshahr estuaries) in summer and winter 2019 using sediment quality indices. In each tributary...

Effect of coconut shell ash as an additive on the properties of green concrete
Solid Waste Management
Concrete is the broadly adopted composite material in the construction arena. The growing need for cost-effective housing is resulting in the depletion of environmental resources such as river sand and gravel, which are essential components in the manufacture of concrete. However, the manufacturing...
