A research was conducted to determine the feasibility of using adsorption process remove boron from aqueous solutions batch technique. Three adsorbent materials; magnesium, aluminum and iron oxide were investigated find their abilities for removal. The effects operational parameters on removal efficiency each material determined.The experimental results revealed that maximum achieved at pH 9.5 ...

Thin films of boron nitride have been obtained by reactive pulsed laser ablation of a boron target in the presence of a 13.56 MHz radio frequency nitrogen plasma. The films have been deposited at several substrate temperatures, using the on-axis configuration, on WC–Co cutting tools, after Co removal by chemical etching (HClyHNO or HFyHNO ). Diamond polycrystalline 3 3 films of increasing thick...

Weakly charged elements, or elements that are not well dissociated in water, are not removed ef®ciently by conventional water-puri®cation technologies. In the production of high-purity water, silica and boron are generally the ®rst ions to breakthrough into puri®ed water when the ion-exchange resin approaches depletion. In this study, the behavior of these two elements was studied through vario...

Electrical activation and redistribution of 500 eV boron implants in preamorphized silicon after nonmelt laser annealing at 1150 °C and isochronal rapid thermal postannealing are reported. Under the thermal conditions used for a nonmelt laser at 1150 °C, a substantial residue of end-of-range defects remained after one laser scan but these were mainly dissolved within ten scans. The authors find...

Boron removal capacity of multi-walled carbon nanotubes (MWCNTs) modified with tartaric acid was investigated in this study. Modification of MWCNTs with tartaric acid was confirmed by Boehm surface chemistry method and fourier transform infra-red (FT-IR) spectroscopy. Experiments were performed to determine the adsorption isotherm and adsorption thermodynamic parameters of boron adsorption on t...

A boron isotope study combined with analyses of elemental boron, lithium, and chlorine is used to suggest that brines from the Dead Sea and on-shore hypersaline thermal springs (Hamme Yesha, Hamme Zohar, and Hamme Mazor) are the products of interaction of evaporated seawater with detrital sediments. The high 6”B values of the Dead Sea brines (55.7 to 57.4%0 versus NBS-951) and the hot springs (...

Highly porous boron nitride nanosheets (BNNSs) were tested as a re-usable adsorbent for the removal of pharmaceuticals from aqueous solution. The BNNSs exhibit both unprecedentedly high adsorption capacities and excellent recyclability while maintaining their high adsorption capacity by a simple regeneration process. These advantages render BNNSs a promising material for water remediation appli...

In this study, it is aimed to treat the wastewater from drilling operations during creation of a natural gas storage area by electrocoagulation (EC) method. Boron and sulfate parameters in were tried be eliminated with help aluminum electrodes. During removal boron pollutants, optimization studies carried out on process time, pH, current criteria. (B) (SO4) concentrations generated measured as ...
