Abstract The Yinchuan Plain has more than 2000 years of history irrigation by diverting water from the Yellow River. Currently, amount diverted River is about 21.7 times formed on plain as a result precipitation and inflow groundwater. Under intensive influence irrigation, changed desert into rich populous area, earning its name ‘South China Beyond Great Wall’, with lakes scattered across just stars in sky. In this research, 17 representative were sampled to analyze study 2 H 18 O content;...
In this study, a Z-Scheme WO3/CoO p-n heterojunction with 0D/3D structure was designed and prepared via simple solvothermal approach to remove the combined pollution of tetracycline heavy metal Cr(VI) in water. The 0D WO3 nanoparticles adhered surface 3D octahedral CoO facilitate construction Z-scheme heterojunctions, which could avoid deactivation monomeric material due agglomeration, extend optical response range, separate photogenerated electronhole pairs. degradation efficiency mixed...
In recent years, the lake area of Chahannur Basin has been decreasing, leading to an increase in salt dust storms. order find out recharge mechanism groundwater Basin, a total 51 and surface water samples were collected. Tritium (3H) isotope Freon (CFCs) used estimate age preliminarily analyze sources recharge. The characteristics hydrogen, oxygen, strontium isotopes are indicate cycle Basin. results show that: (1) Two dating methods, tritium (CFCs), suitable for semi-quantitative (2)...
In this article, Z-scheme NiO/α-MoO3 p-n heterojunction is successfully synthesized by a facile hydrothermal route. The phase and nanostructures are researched through series of characterizations, such as XRD, SEM, TEM, EDX, XPS DRS. It confirmed that the NiO nanoparticles deposited homogeneously on one dimensional α-MoO3 nanobelts heterojuction constructed at interface NiO. Photocatalytic activity as-synthesized photocatalysts investigated photodegradation methylene blue (MB) under...
Strontium is a kind of trace element. Groundwater containing strontium called mineral water when its content reaches level that beneficial for human physiology. Some groundwater resources in Shijiazhuang are rich strontium. In this study, samples collected from 103 sites were studied the hydrochemical characteristics and formation mechanism system City. The methods source provenance analysis, factor correlation runoff condition analysis carried out study. results showed eastern higher than...
The geographic location of Yongqing County is optimal, covering the center Beijing, Tianjin, and Baoding triangle. However, economic social development in recent years has resulted negative impacts on groundwater. Therefore, investigating current status groundwater chemistry great significance to provide a useful basis for future studies quality assessment. aim this study assess hydrochemical characteristics formation mechanisms unconfined aquifers using descriptive statistical multivariate...
This paper studies the spatial distribution characteristics and controlling factors of groundwater chemistry in Chahannur Basin. One hundred seventy shallow samples (50 m shallow) are collected, seven ions, pH, TDS, TH, iron, manganese, COD, barium other indicators, detected. Piper triplex graph, Gibbs model, ion ratio, analysis variance Kriging interpolation used to carry out research. The results show that bicarbonate water is main chemical type Basin, which accounts for 65.23%, chloride...
Groundwater is an important resource for domestic use and irrigation in the Yinchuan region of northwest China. However, quality groundwater this declining due to human activities, with adverse effects on health. In order study chemical elements health, health risk drinking was calculated based actual situation China U.S. Environmental Protection Agency (USEPA) model. Moreover, sensitivity contaminant exposure water wells quantified using Monte Carlo simulation minimize uncertainty...
To investigate the hydrogeochemical characteristics of shallow groundwater and evaluate salinization state in Cangzhou, China, two sampling campaigns have been conducted. In summer, 33 samples, 3 seawater samples 5 river water were collected. winter, 22 The hydrochemical type was determined by Piper diagram. Evolution mechanisms analyzed Gibbs trend de-salinization or facies evolution grade evaluated both intrusion quality index (GQI SWI ) attribute recognition model based on entropy weight...
Groundwater resources in North China are scarce, and nitrogen pollution, especially ammonia groundwater is a severe environmental challenge for this area. In context, the effects of differentaquifer media on adsorption Hutuo river plain, north were investigated study. particular, aim study was to investigate influence Eh, clay particle organic material content adsorption. The found that Eh affected migration transformation NH4+-N aquifer media. When less than or equal 14%, reached...
Abstract The rapid development of the social economy and influence human activities can lead to aggravated groundwater pollution. Groundwater safety is premise residents' health. Therefore, studying sustainable utilization health risks quality important. potential were evaluated in Shijiazhuang area, which located North China Plain this paper. Based on 159 samples collected study As, Cr 6+ , Ni, Pb, F − NO 3 humans from oral skin contact. Results risk assessment showed that average...
This study was carried out to evaluate the groundwater quality in Huangbizhuang town, which is an important water source for Shijiazhuang and Beijing, China. Fifty-six geo-referenced samples were collected from pumping monitoring wells July September 2018. The investigated applicability of two weighting methods, expert method, principal component analysis assessment evaluated status leading causes pollution by chemical index multivariate statistical methods. results show that overall good,...
