Dialdehyde 8-aminoquinoline starch (DASQA) was synthesized by the reaction of dialdehyde starch (DAS) and 8-aminoquinoline and was used to adsorb various ions from aqueous solution. DASQA was characterized by Fourier transform infrared (FT-IR) spectra, thermogravimetric analysis, X-ray diffraction analysis. The adsorption properties of the polymer for Pb2+, Cu2+, ...

This paper reports the effect of various process parameters on the removal of chromium from aqueous solution using formaldehyde–treated timber industry waste (sawdust). The adsorbent was characterised by Scanning Electron Microscopy (SEM) and Energy Dispersive X–Ray Analysis (EDAX). Influence of chromium concentration, pH, adsorbent dose and contact time on chromium removal from aqueous solution ...

This paper communicates the distribution of carbon atoms in a single poly-cyclic aromatic (PCA) layer (graphene) in Tikak coal from Assam, India. The pair distribution function (PDF) analysis performed indicates no evidence of any graphite like structure in this coal. The aromatic fraction is observed to be 74% with the aliphatic fraction correspondingly estimated to be 26% in this coal. The ...

Spent grain, the low-cost and abundant biomass produced in the brewing industry, was functionalized with thiol groups to be used as an adsorbent for Hg(II) removal from acidic aqueous solution. The adsorbents were characterized by the energy-dispersive X-ray analysis (EDAX) and Fourier transform infrared (FTIR) spectroscopy. Optimum pH for Hg(II) adsorption onto the thiol-functionalized spent ...

The aim of this study is to investigate the conditions for the removal of manganese ions from synthetic groundwater by oxidation using KMnO4 to keep the concentration below the allowed level (0.05 mg/L). The process includes low-level aeration and addition of KMnO4 in a Jar test system with Mn2 +  concentration of 0.50 mg/L, similar to that of natural groundwater in Taiwan. Different parameters ...

Ruthenium nanoparticles stabilised by polyaromatic amine-containing compounds (aminoethylcarbazole, aminoanthracene and aminoanthraquinone) were synthesised in solution using three different preparative methods, namely modified polyol reduction, borohydride reduction and phase-transfer method, respectively. Their product yields, particle sizes and size distributions were compared accordingly. The ...

In memory of the 50th anniversary after the foundation of HORIBA, Ltd., the "Masao Horiba Awards" was established after the founder's name. In 2006, the theme for the 3rd Masao Horiba Awards was "X-ray analysis", and among many excellent candidates, this prize was awarded to 3 people, and a special award was awarded to 1 person. The purpose of the 2006 Masao Horiba Awards, the circumstances from ...

Graphite plates were Ar+ ion-irradiated with and without a simultaneous Fe supply at room temperature. The surfaces ion-irradiated without an Fe supply were covered with densely distributed conical projections with a carbon nanofibre (CNF) on the top. The CNFs thus grown were 20-50 nm in diameter and 0.3-2 µm in length. By contrast, the graphite surfaces ion-bombarded with a simultaneous Fe ...

LTV Steel's Use of Essential EH&S Enables Environmental Pros To Do Much More Than Just Crunch Numbers The Challenge: LTV Steel's (now Mittal Steel) internal Environmental, Health & Safety (EH&S) solutions were adequate to do the job they were being called upon to do, but it was clear they would soon be outdated. The solutions resided on a mainframe and data had to be manually keyed in ...

We are now developing a system which allows the visualization of the structure and tissue associated with breast cancer, which is difficult to achieve with conventional mammography, by utilizing X-ray refraction. This system is expected to achieve an approximately 1000-fold higher contrast and high spatial resolution at low dose; compared to techniques by use of X-ray absorption. Monochromatic ...
