Graphene aerogel (GA) was synthesized by chemical reduction of graphene oxide (GO) using ethylene diamine as a reducing agent, which was then followed by a freeze-drying process. In this work, we produced GA by hydrothermal process followed by freeze-drying. The produced adsorbent was then deployed to study the TC adsorption process.

In this study, we present the experimental evidence demonstrating the utility of electrical double layer (EDL)-induced ion accumulation, using sodium (Na+) ion in water as a model substance, on a negatively charged nanostructured surface, specifically thermally grown silicon dioxide (SiO2). This novel approach, termed Ion Surface Accumulation (ISA), aims to enhance the performance of nanostructured porous silicon (PSi) interferometers in optical refractometric applications.

This article, we present a thorough and straightforward hydrothermal method towards the production of reduced graphene oxide templated MIL-53(Fe) hybrids RGO@MIL-53(Fe). The structural characteristics of created hybrids were identified by using BET, FESEM, powder X-ray diffraction, and FTIR techniques. Methylene blue (MB) dye (a model water pollutant) was used to evaluate H2O2-assisted photo-catalytic efficiency of RGO@MIL-53(Fe).

In porous aquifers, the central-to-sea cross-section highlights meteoric water dominance from rain and surface sources. Groundwater undergoes exchange-absorption with silicate minerals, enriching Ca2+ and Mg2+ (reducing Na+). Seaward, dissolution and leaching of salts in marine-origin sediments (mQ2, mQ13, mQ12-3, and mN22) prevail. The results of this paper provide necessary information for the effective management of groundwater quality.

The Cuu Long delta is affected strongly by mass water from rivers of the MeKong river system such as Tieu, Dai, Ham Luong, Co Chien, Cung Hau, Dinh An and Tranh De (Hau river). The estuaries of Cuu Long delta are large with a huge amount of sediment (about 100 million tons per year) and high tide (about 4.2m) made the large tidal flats with high level of biodiversity, which is an important resource for aquaculture.

In study "Impact of urbanization on seawater quality in Quang Ninh province" the authors use indicators to assess the level of water pollution, such as chemical and microbial pollution and measure the impact of urban factors, such as population growth, wastewater discharge and water consumption. In the survey results of seawater quality in two seasons, the rainy season and the dry season, there is a difference in some specific hydrological indicators, such as Coliform exceeding the allowable threshold in the dry season and iron and ammonium content tending to increase.
