Infrared spectra and thermogravimetric (t.g.a.) and differential thermal (d.t.a.) analyses are reported for Cd(OH)2 obtained by the action of dilute ammonia solution on aqueous solutions of cadmium chloride, sulfate, and nitrate. The analyses indicate that the precipitated cadmium hydroxide from these solutions is often admixed with basic salts.

Spectral differences between aqueous solutions of NaCl and KCl have received minimal attention in previous research due to strong similarities between the two salts and the lack of motivation to differentiate between them. Correlations between salinity and absorbance have been developed previously with varying degrees of linearity but have not been tested to saturation. This work will demonstrate that correlating spectral measurements and the concentration of NaCl and KCl in water can be extended up to the saturation point of both salts and that solutions of these salts with unknown concentrations can be distinguished. Spectral data for samples of NaCl and KCl in single-salt solutions were collected up to saturation and correlations were developed for differentiating between solutions of the two species. These correlations were able to correctly identify the solution type for all solutions in the test set and estimate their concentrations with an average error of 0.9%.

Cadmium Salt

Among cereals, a special place is occupied by wheat as the main food of humanity and in improving the country's economy. The main task of breeding is to produce valuable wheat varieties that are stable to the unfavorable external environment of various natural climatic zones of Kazakhstan, consisting of a combination of valuable features. The prospects for the use of mutants in the process of hybridization are reflected in the achievements of world and domestic selection. The effect of various solutions of chemical compounds on the plant was observed from the first days during the growth of wheat sprouts. The growth of the first sprout of seeds treated with a certain solution of cadmium chloride and zinc chloride - 0.01%, the activity of cell division and structural disorders of chromosomes were manifested by variability in the varieties Kazakhstani3, Shagala, Zhenis and Lutescens 32. When treating dry wheat grain with a concentration of 0.1% cadmium chloride, it brought the growth of the Sprout to a lethal state, 0.01% inhibited the growth of the Sprout for 4 days, and in a 0.001% solution, the growth rate of the control grains was the same. On the contrary, a 0.1% vertical solution of zinc chloride inhibited the growth of the Sprout for 1 Week, 0.01% for three days. Among the studied concentrations, a 0.01% solution of cadmium chloride inhibited the growth of sprouts, causing chromosomal aberrations and morphological variability in cell division. Therefore, a concentration of 0.01% of cadmium salt was obtained as an optimal concentration to expand the limits of variability in wheat. In this regard, in our study, it was found that a 0.01% solution of cadmium chloride is an effective concentration that expands the limits of variability in wheat. The effect of this amount of solution leads to morphological changes in the plant (Binding of the stem, elongation of the earlobe, increase in the number and weight of grains in the headlobe, increase in the weight of 1000 grains, etc.), and changes in the characteristics of the M1 - M4 offspring are constantly inherited. Mutant lines L1, L2 and L3 differ in valuable breeding characteristics under the influence of a 0.01 percent solution of cadmium salt were obtained for the Kazakhstanskaya 3 and Shagala varieties. A genetic analysis of the type of development of these altered lines was carried out, as a result of which a long (16 cm) dense ear (0.80) changed from the Gull variety to a prismatic plant of the control variety (0.50), as a result of hybridization, its summer type (from the vrn gene) to the autumn type (Vrn gene). As a result of the study, Kazakhstanskaya 3, Kazakhstanskaya mutant 3 varieties contain the genes Vrn 1, Vrn 3. Well, it was found that Shagala varieties consist of the genes Vrnl, Vrn2. Varieties containing the genes Vrn1, Vrn3 show rapid maturation. However, they differed from each other in the period of intoxication.

Quantitative Separation

Extraction of the histone of thymonucleoprotein with alcohol and salt has been studied with varying concentrations of alcohol, sodium chloride, and nucleoprotein and with varying pH and temperature. The addition of 0.5–1.0 volumes of ethanol to a solution of nucleoprotein (approximately 1 mgm. N/ml.) in 3 M sodium chloride has been found to effect an almost quantitative separation of desoxyribonucleic acid and protein. It has proved feasible to prepare concentrated aqueous solutions of the extracted protein by successive dialysis against strong salt solutions at −10 °C. and against distilled water at 5 °C. followed by pervaporation at 5 °C. The properties of the isolated nucleate have indicated a highly polymerized product.
