Box Tehran, Iran. The received products were investigated by XRD. Depending on the conditions of reaction temperature, heating rate, mass of sample, surrounding atmosphere thermal decomposition leads to chromium oxides Cr2O3, different size and porosity or specific area of the forming grains. Calculations related to mass loss were also reported. Due to their chemical and physical characteristics, chromium compounds are used in a wide variety of industries all over the world [ 1 , 2 , 3 , 4 , 5 , 6 ]. One of the most important characteristics of the chromium concerns its reactions to acids and bases as well as to air, a process known as oxidation. Some are the end product of a desired process but most of them are undesired byproducts known as disturb compounds [ 7 , 8 , 9 ]. Chromite is one of the most significant compounds used in steel industries [ 8 , 9 , 10 ]. The morphology of these compounds was also studied [ 11 ]. Other Experiments demonstrated that the presence of nitrogen in the substrate is always a precursor to breakdown of the oxide layer and does not result from diffusion through the Cr 2 O 3 Layer [ 14 ]. The present research intended to investigate the thermal properties of chromium nitrate under different temperature conditions.

A single-base-pair substitution of CT at the nucleotide sequence was found which resulted in a nonsense mutation TGA and terminated the protein synthesis of factor IX at amino acid residue The single-base change occurred as a classic CG dinucleotide alteration to TG or CA , a common mechanism for point mutations in mammals.

In thermogravimetric analysis TGA , a sample is continually weighted while heating, as an inert gas atmosphere is passed over it. Many solids undergo reactions that evolve gaseous byproducts. In TGA, these gaseous byproducts are removed and changes in the remaining mass of the sample are recorded. Three variations are commonly employed:. Figure 1 shows a TGA curve in green. Raja and Andrew R. Barron chemlibretext link. Data from thermogravimetric analysis is often shown by a graph representing mass as a function of temperature for dynamic TGA. For static TGA, mass is instead plotted as a function of time at a given temperature. Quasistatic TGA produces multiple mass vs.

MIL Fe, Cr and MIL Cr were synthesized by the hydrothermal method and applied to the adsorptions of five aromatic amines from aqueous solutions. The adsorption mechanism of three MOFs and the effects of the structures of MOFs on the adsorption of aromatic amines were discussed. The results show that the cavity system and suitable hydrogen bond acceptor were important factors for the adsorption for five aromatic amines of aniline, 1-naphthalamine, o-toluidine, 2-aminonitrotoluene and 2-nitroaniline: a the saturated adsorption capacity of aniline, 1-naphthylamine and o-toluidine on MIL Fe were As a typical organic compound, aromatic amines are widely used in the production of dyes, pharmaceuticals or resins [ 1 ]. In the industrial production of dyes, aromatic amines can flow into the water in large amounts, causing water pollution. Currently, azo dyes are widely found in textiles, paints, plastics and rubber.
