Artificial neural network (ANN), pseudo second-order kinetic, and gene expression programming (GEP) models were constructed to predict removal efficiency of Lanaset Red G (LR G) using lentil straw (LS) based on 1152 experimental sets. The sorption process was dependent on adsorbent particle size, pH, initial dye concentration, and contact time. These variables were used as input to construct a ...

Rotaviruses are the leading cause and coronaviruses are the major contributors of acute gastroenteritis in the young of various mammalian and avian species. Despite numerous trials and decades of research, vaccines have limited efficacy particularly for calves. As an alternative method of controlling infection, we have investigated broad spectrum antiviral agents that are not discriminatory amo...

Anthracite was used as an adsorbent to remove excess phosphate from wastewater. Anthracite used in the present study is environmentally friendly and of cost effective. The adsorption study was carried out using different particle size of adsorbents, different concentration of phosphate solution ranging from 25.0 mg/L to 100.0 mg/L, different pH values ranging from 0.5 to 11.5 along with differe...

Batch sorption experiments were carried out to remove As(III) from aqueous solution by using iron based commercial adsorbent Bayoxide. The effects of various experimental parameters, such as initial concentration, contact time and solution pH on the adsorption of As(III) on adsorbent was investigated. The adsorption density increased with increased initial arsenic concentration and contact time...

Polyacrylonitrile (PAN)-oxime-nano Fe2O3 was used as an adsorbent for the removal of fluoride from water. The influences of contact time, initial fluoride concentration, and adsorbent dosage were investigated by batch equilibrium studies. The rate of adsorption was rapid with equilibrium being attained after 100min. The Langmuir isotherm model was found to represent the measured adsorption data...

The present study focuses on the use of Corn cob as an effective and efficient adsorbent for the removal of Ni (II) from aqueous solution. The influence of Physico-chemical parameters such as Adsorbent Dosage, Contact time, pH and Initial concentration has been examined in Batch studies. The initial and residual concentration of Ni (II) was analyzed using UVDouble Beam absorption spectrophotome...

Introduction: Mercury is one of the toxic metals that damages the nervous system and kidneys. Therefore, monitoring of mercury vapors in the environments is essential. .Material and Method: A new adsorbent was made from silver nanoparticles on a bed of quartz. The nano-adsorbent was capable for sampling of the trace amounts of mercury vapor from air. In this study, the required mercury vapor ...

A limited amount of DNA extracted from single cells, and the development of single cell diagnostics make it necessary to create a new highly effective method for the single cells nucleic acids isolation. In this paper, we propose the DNA isolation method from biomaterials with limited DNA quantity in sample, and from samples with degradable DNA based on the use of solid-phase adsorbent silicon ...

A new concept for non-catalytic NO removal from combustion flue gas is being developed at the University of Kentucky Center for Applied Energy Research (CAER). Flue gas cleanup would be achieved through the use of activated carbons for the selective capture of NOx at stack temperatures between 70-120°C followed by desorption of a concentrated stream of NO, at elevated temperatures, near 140-150...
