Defluoridation of Aqueous Solution by Graphene and Graphene Oxide Nanoparticles: Thermodynamic and Isotherm Studies

Fluoride, a non-essential element, can enter water resources through several natural processes and human activities. The benefits and risks of fluoride depend on the concentration of this anion on drinking waters. In the present study, the performances of graphene and graphene oxide nanoparticles were investigated for the removal of fluoride from aqueous solution. In the present resea...

scour modeling piles of kambuzia industrial city bridge using hec-ras and artificial neural network

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

Comparative Study of Defluoridation from Water using Waste Materials as Adsorbents – A Review

Fluoride is one of the most abundant constituents occurring in the groundwater in many parts of the world, posing a potential threat to human health. The permissible limit of fluoride concentration in drinking water is 1.5mg/L according to WHO guidelines. In India, 25 million people in 19 states and union territories have already been affected and another 66 million are at risk, including 6 mil...

Sorption isotherm and kinetic modeling of aniline on Cr-bentonite.

In this paper, the sorption characteristics of aniline on Cr-bentonite prepared using synthetic wastewater containing chromium was investigated in a batch system at 30 degrees C. The effects of relevant parameters, such as pH value of solution, adsorbent dosage and initial aniline concentration were examined. The experimental data were analyzed by the Langmuir and Freundlich, and Temkin models ...
