The polypyrrole (PPY/TW) and magnetic (MG/TW) composite with tea waste (TW) was prepared used as an adsorbent for PO43− ions removal from aqueous media. were characterized SEM FTIR techniques. Batch study conducted to investigate the effect of different reaction parameters on adsorption ions. native TW, PPY/TW, MG/TW showed 7.2, 7.3, 7.9 (mg/g), respectively, using 0.05 g dose 10 mg/L initial c...

The application of combined research methods, such as hydrochemical and isotopic analyses, facilitates understanding the origin water constituents migration contaminants in aquatic environment. presented study attempts to identify contamination sources affecting quality within Kozłowa Góra reservoir catchment area (southern Poland). A total 100 samples were collected from surface (the Brynica r...

PO4(3-) and SiO3(2-) are often used as modifier to improve stability and aggregating ability of the iron-base coagulants, however, there are few reports about their detailed comparison between the coagulation performance and mechanisms. In this study, three coagulants--polyferric phosphoric sulfate (PFPS), polysilicon ferric sulfate (PFSS), and polyferric sulfate (PFS) were synthesized; their s...

In high altitude environments, extreme levels of solar radiation and important differences of ionic concentrations over narrow spatial scales may modulate microbial activity. In Salar de Huasco, a high-altitude wetland in the Andean mountains, the high diversity of microbial communities has been characterized and associated with strong environmental variability. Communities that differed in lig...

The efficiency of hydrogen peroxide evolution reaction (H2O2ER) by photoanodic water oxidation is normally limited low yield and poor selectivity. In this work, the surfaces Mo doped BiVO4 are modified Co2+ PO43- ions (CPMB), which has been used as photoanode with improved H2O2 optimal rate CPMB ca. 0.23 µmol·min−1·cm−2, corresponding to 2.5 times pristine photoanode, faradaic for H2O2ER 26%. s...

Abstract Wetlands deliver many ecosystem services but are under continuous threat due to various anthropogenic activities. The present study has been carried out examine the suitability of Kusheshwar-Asthan wetland's water for agriculture. A total 57 samples were analyzed quality parameters like electrical conductivity, pH, temperature, dissolved oxygen (DO), major cations (Ca2+, Mg2+, Na+, K+)...
