AbstractA simple, selective and rapid determination procedure for Th, Zr and Sc in rock samples using adsorbent silica modified with arsenazo-III is described. Silica modified with arsenazo-III (SAR-III) was synthesised by a single step process in presence of cationic surfactant cetyltrimethylammonium bromide. Effect of pH, amount of adsorbent, con...
The crystal structure, H bonding and chemical composition of hydroxylherderite from the Bennett pegmatite, Buckfield, Oxford County, Maine, USA were investigated by single-crystal X-ray diffraction and neutron Laue diffraction, electron microprobe analysis in wavelength-dispersive mode, inductively coupled plasma-atomic emission spectrometry and po...
AimConventional antiepileptics (AEDs) have been shown to alter the homeostasis of copper, zinc, and selenium in persons with epilepsy (PWE). The effects of newer AEDs on trace elements have not been addressed yet. This cross-sectional study evaluated trace elements and electrolytes status in PWE on conventional and newer AEDs treatment. MethodsA to...
•WTRs addition slightly enhanced nitrification potential of lake sediment.•WTRs addition increased AOB and NOB abundances in lake sediment.•WTRs addition increased AOB and NOB diversities.•WTRs addition had minor effects on AOB and NOB morphologies.•WTRs reuse for lake internal P loading control would be beneficial to nitrification.

Mg–Al layered double hydroxide (Mg–Al LDH) doped with Fe2+ was prepared by dropwise addition of a mixed solution of MgCl2, FeCl2, and AlCl3 to NaOH solution at a constant pH. The Fe2+-doped LDH was found to be able to remove Cr(VI) from an aqueous solution through the anion exchange of Cr2O72- with the intercalated Cl−, the production of Cr(OH)3, a...

•The glycerol-stocked turbine oil-degrading bacterial consortium Tank-2 was revived.•Revived Tank-2 exhibited an activity equivalent to that of the original.•Revived Tank-2 also degraded various types of oil and turbine oil in wastes.•The microbial community structure of two consortia was significantly different.•Bacterial strains could adjust thei...
Normal cornstarch (NC) was chemically modified by octenylsuccinic anhydride (OSA) and Al2(SO4)3. The effects of the concentration of NaOH, OSA, and Al2(SO4)3 on the properties of modified starch(OS-starch-Al) were investigated. The OS-starch-Al was characterized by repose angle, activation index, inductively coupled plasma-atomic emission spectrome...

Concentration of heavy metals in blood and urine of rabbit after inhaling three different kinds of cigarette was studied through the animal passive smoking pattern. The samples were prepared by nitric acid solution digestion and determination of seven kinds of heavy metals including Hg, Se, Sn, Pb, Cd, Ni and Cr was performed by inductively coupled...
