Quantitative Properties

We propose a simple method to investigate both the qualitative and quantitative properties of titanium tetrachloride. The selection and concentration of the employed solvent were found to be very important in the analysis of highly reactive titanium tetrachloride (TiCl4). Herein, we employed various concentrations of an acid solution to serve as a stabilizing medium. Qualitative analysis was performed via Fourier transform-infrared spectroscopy (FT-IR) and scanning electron microscope-energy dispersive spectroscopy (SEM-EDS). Additionally, the quantitative analysis was performed via inductively coupled plasma optical emission spectroscopy (ICP-OES). We concluded that both the qualitative and quantitative properties of titanium tetrachloride could be easily measured using a specific acidic solvent as a medium.

The biomass ofVaucheria sessilisforms algal mats in many freshwaters. There is a need to find the method of algal biomass utilization.Vaucheria sessilisis a rich source of micro- and macronutrients and can be used as a soil amendment. In the paper, the elemental composition of enriched, via bioaccumulation process, macroalga was investigated. For this purpose, two independent techniques were used: scanning electron microscopy with an energy dispersive X-ray analytical system (SEMEDX) and inductively coupled plasma optical emission spectroscopy (ICP-OES). The biomass was exposed to two microelemental solutions, with Cu(II) and Zn(II) ions. After two weeks of the experiment, macroalga accumulated 98.5 mg of Zn(II) ions in 1 g of dry biomass and 68.9 mg g−1of Cu(II) ions. Micrographs performed by SEM proved that bioaccumulation occurred. Metal ions were bound on the surface and in the interior of cells. Mappings of all cations showed that in the case of the surface of biomass (biosorption), the elements constituted aggregations and in the case of the cross section (bioaccumulation) they were evenly distributed. The algal biomass with permanently bound microelements can find an application in many branches of the industry (feed, natural fertilizers, etc.).

Through an alkylation reaction under alkaline conditions, isobutyl was introduced to chitosan to form isobutyl-chitosan. Isobutyl-chitosan-Ca (II) complex was synthesized at pH 6.0 by a reaction of isobutyl-chitosan and calcium chloride. The structure of isobutyl-chitosan-Ca (II) complexes was characterized by ultraviolet-visible diffuse reflectance spectrum (UV-Vis) and FT-IR spectrum, and the content of calcium was measured by inductively coupled plasma-optical emission spectrometry (ICP-OES). The FT-IR spectra of isobutyl-chitosan and chitosan showed that structure of isobutyl-chitosan-Ca (II) complexes was obviously different with isobutyl-chitosan. Results of UV spectra showed that the maximum absorption of isobutyl-chitosan and isobutyl-chitosan-Ca (II) were at 310 nm and 324 nm, respectively. The content of calcium was 1.6026%, measured by ICP-OES.
