Biosorption of Pb(II) Ions through Nanostructured Teff Straw based Magnetized Activated Biocarbon: Aspects on Modeling, Optimization, and Kinetics
Innovative environmental solutions
In this study, activated carbon (AC) was prepared from teff grass straw via chemical activation and microwave-assisted pyrolysis. The AC was modified by magnetization followed by it was characterized by particle size, FTIR, XRD , thermogravimetric study, pore size, and magnetic properties. Further...
Elimination of malachite green by modified Fenton like process. Application of Box Behnken design
Advanced Oxidation Processes for Wastewater treatment
The aim of this work was to investigate an advanced oxidation process for removing malachite green from aqueous solutions using a modified Fenton-like process. An experimental Box-Behnken design was applied to determine the optimal conditions by examining the effects of catalyst concentration ([Fe 2...
An Automatic Data-Driven Long-term Rainfall Prediction using Humboldt Squid Optimized Convolutional Residual Attentive Gated Circulation Model in India
Climate change mitigation and adaptation
Precise long-term rainfall forecasting is becoming progressively significant, predominantly in periods of fluctuating weather circumstances. These prophecies are indispensable for several areas, including agronomy, water resource supervision, flood attentiveness, and effluence monitoring. This...
Efficient Biomedical Waste Management: Optimizing Segmentation and Classification with EnU-Net-DNN-BMWC
Solid Waste Management
In India, biomedical waste (BMW) management is governed by strict regulations to mitigate health and environmental risks. It includes materials such as sharps, infectious wastes, pharmaceuticals, and non-hazardous items contaminated with potentially infectious substances. Proper management and...
Nitrate source analysis of underground drinking water sources in Zhangjiakou main urban area and its health risk assessment
Water Quality
In order to investigate the main pollution factors of underground drinking water sources in semi-arid agricultural areas in China, and to reveal the threatening influence of pollutants on the normal water security of local society. Single-factor evaluation index, principal component analysis, basic...
Groundwater quality assessment for drinking and irrigation purposes in arid to semiarid region of Indus Basin of South Punjab, Pakistan
Water Quality
As the groundwater pollution is increasing, it is crucial to assess groundwater quality and characterize hydrogeochemistry accurately for long term water supply. In this study groundwater samples were collected from 120 locations from Bahawalpur district and analyzed for electrical conductivity (EC)...
Effective removal of Calcium and Magnesium Ions from boiler feed Water using Polyacrylonitrile supported titanium tungstovanadate composite ion exchange nanofiber
Water and Wastewater Treatment
The challenge posed by the presence of calcium ions (Ca 2+) in process streams is attributed to its adverse effects on the heat transfer efficiency of process equipment. In this study, a novel electrospun nanofibrous composite was synthesized by combining polyacrylonitrile (PAN) with well...
Optimization of the Freeze Crystallization Process for Recovering of Copper (II) Sulphate from Electroplating Wastewater Using Response Surface Methodology (RSM)
Water and Wastewater Treatment
For the copper-containing electroplating wastewater generated by a semiconductor company, the recovery of copper salts by progressive freeze crystallization and its process parameters were experimentally optimized and studied. Based on the results of single-factor experiments, according to the...
Air Pollution and Urban Economic Growth: A Study Based on Dynamic Models
Environmental Management and Policies
With China's economic growth, the issue of air pollution has become increasingly prominent. As the core of political and economic development, 184 major cities in China face severe air pollution and significant environmental pressures due to high population density. Consequently, China has...
The effect of artificial metakaolin coarse aggregate on the mechanical and durability properties of lightweight geopolymer concrete
Solid Waste Management
This study presents a unique methodology for investigating the properties of Metakaolin Coarse Aggregates (MCA). The NaOH ratios were varied as 8M, 10M, 12M, and 14M, while the NaOH to Na 2SiO 3 ratio was maintained at 0.5 entire study. The liquid-to-binder ( L/B) ratios set at 0.3, 0.35, and 0.4...
