Boron minerals are very useful for various industrial activities, such as glass industry and detergent industry, due to its mechanical and chemical properties. During the production of boron compounds, many of these are introduced into the environment in the form of waste. Boron is also an important micro nutrient for the plants to vegetate but if it exists in high concentrations, it could have...

The need to clean-up heavy metal contaminated environment can not be over emphasized. This paper describes the adsorption isotherm studies of Cd (II), Pb (II) and Zn (II) ions from aqueous solution using unmodified and EDTA-modified maize cob. Maize cob was found to be an excellent adsorbent for the removal of these metal ions. The amount of metal ions adsorbed increased as the initial concentr...

Investigations on the effectiveness and inhibitory activity of isolated flavonoid (Rutin) from Spermacoce hispida plants against corrosion metal in a 1M HCl acidic solution include mass loss analysis, potentiostatic curves, electrochemical methods. Plant extracts have been found to exhibit excellent properties metals different environments. The base metal's ability stop improves when green inhi...

N ̶ Benzylidene 4 Methoxyaniline (NB4MA) schiff base was synthesized and investigated corrosion behavior of mild steel (MS) in 1M HCI 0.5M H2SO4. The efficiency studied by means mass loss electrochemical techniques. studies confirm that Ecorr displacement about 32mV confirms anodic cathodic type inhibitor. positive direction potential curves confirmed adsorption on metal surface. Langmuir isothe...

zinc (zn) availability and mobility in soils is controlled by its interaction with the soil matrix and amendments. contradicting evidence has been reported for factors influencing zn behavior in soils. the aim of this study was to investigate the zn sorption in selected acid, calcareous and gypsiferous soils with different background electrolytes (na+, k+ and h2po4, no3 and cl backgrounds). iso...

In this work, a new method based on the modified Enskog theory (MET) is presented for calculation of transport properties at high densities ρ > ρc). The main limitation of using the MET is lack of experimental data for co-volume, b0. We have substituted b0 from hard sphere (HS) theory nd zero density transport properties from the kinetic theory of gases for HS in the MET expression, because of ...

Bernal suggested that clays might have played a significant role in primitive earth through the process of concentration and adsorption of the biologically formed biomonomers and thus protecting them against hydrolytic fission.Adsorption of adenine was studied in presence of montmorillonite clay with or without cations Ca+,Cu+,Mg+.Studies carried out have shown that adsorption of adenine was de...

The purpose of this study is to investigate the capacity of natural Turkish zeolite for NH4-N removal from landfill leachate. The effects of modification and initial concentration on the removal of NH4-N from leachate were also investigated. The kinetics of adsorption of NH4-N has been discussed using three kinetic models, i.e., the pseudo-second order model, the Elovich equation, the intrapart...
