Bu çalışmada, çimentolu macun dolgu (ÇMD) karışımında sülfürlü maden atığı (S-MA) yerine ikame (ağırlıkça %10) olarak doğal alkali malzemelerin (kalsitik kireçtaşı: KK ve dolomitik DK) kullanılmasının ÇMD’nin uzun dönem çevresel davranışına etkileri araştırılmıştır. amaçla, ÇMD numuneleri 360 güne kadar dinamik tank liçi testlerine tabi tutulmuş elde edilen sızıntı suları üzerinde pH, sülfat (S...

The assessment of the suitability and status irrigation water quality from aspect its potential negative impact on soil salinization mapping spatial distribution within area three Morava rivers, which includes South, West, Great basins, was purpose this research. A total 215 samples were tested, their evaluated based analysis following parameters: pH, electrical conductivity (EC), dissolved sal...

Shuangliao City is an important part of the Xiliaohe Plain, and one most bases grain production in north China. Therefore, it to ascertain hydrochemical characteristics groundwater their causes evolution laws Plain provide guidance agriculture development ecological improvement. After collection detailed data identification flow field, we studied identified types by zone with mathematical stati...

Abstract The role of high-valent Fe has rarely been explored in persulfate-based heterogeneous reaction. Herein, the existence Fe(IV) is verified a visible light-assisted FeTiO3/persulfate system using methyl phenyl sulfoxide as probe. FeTiO3/persulfate/light capable selectively degrading aromatic compounds with lower ionization potentials including tetracycline and bisphenol A by photo-generat...

Air pollution is becoming increasingly serious along with social and economic development in the southwest of China. The distribution characteristics particle matter (PM) were studied Chengdu from 2016 to 2017, changes PM bearing water-soluble ions heavy metals secondary analyzed during haze episode. results showed that at different levels, more likely be enriched fine particles may used as a t...

The chemical composition dataset of Aerosol Reanalysis NASA’s Modern-Era Retrospective Analysis for Research and Application, version 2 (MERRAero) has not been thoroughly evaluated with observation data in mainland China due to the lack long-term components data. Using 5-year PM10 mass concentrations compositions obtained from routine sampling measurements at World Meteorological Organization G...

Assessment of groundwater quality is important for drinking water, especially rural populations. The aim this study was to assess the human consumption by integrating water index with geographic information system (GIS) eventual interpretation Meknes area quality. Eight wells and two springs were investigated between February 2013 2014. In light analysis results, spatial distribution maps chose...
