Fluoride adsorption onto an acid treated lateritic mineral from Kenya: Equilibrium studies
Adsorption of fluoride (F) ions from water using acid treated lateritic mineral (LM-1) from Kenya was studied by batch experiments. The effect of acid-treatment of adsorbent and change in temperature, mass of LM-1, pH and selected competing ions was evaluated. The adsorption process was strongly influenced by temperature, pH and adsorbent dosage. The percentage F removal increased the presence of the nitrate...

Metals in water samples from an urban lagoon in Tabasco, Mexico
Las Ilusiones lagoon is located in Villahermosa city, Mexico. Lack of a steady source of water, contaminants inflowing lagoon through residual and pluvial water drain from populated areas that surround it, and garbage accumulated on banks of the lagoon, have caused an alteration in its auto-purification capacity, producing eutrophication of its waters. The aim of this study was to analyze metals dissolved in...

Deflouridation of water using physico-chemically treated sand as a low-cost adsorbent: An equilibrium study
In this study, heat and chemically treated sand was applied as an adsorbent for the removal of fluoride ions from aqueous solutions. The influence of different parameters such as calcination time, dosage, initial fluoride concentration and pH were evaluated. Results indicated that activated sand can be used for defluoridation of water. This can be achieved by coating sand with 10% Fe2O3, a calcination time of...

Analysis of some meteorological parameters using artificial neural network method for Makurdi, Nigeria
The mean daily data for sunshine hours, maximum temperature, cloud cover and relative humidity data, were used to estimate monthly average global solar irradiation on a horizontal surface for Makurdi, Nigeria. The study used artificial neural networks (ANN) for the estimation. Results showed good agreement between the predicted and measured values of global solar irradiation. A correlation coefficient of...
