“…Excessive concentrations or the accumulation of a number of substances could affect human health and the quality of the environment. Modern research confirms the relevance of innovative ways of purifying water and soil from heavy metals and other pollutants [84][85][86][87]. The use of research methods involving spectrometry allowed us to talk about the wide possibilities of its application [88].…”

This publication presents the results of studies of the bottom sediments (sapropels) of lakes in the North Kazakhstan region. The purpose of this study is to identify the possibility of using sapropels from the lakes of the region in obtaining innovative fertilizers for organic farming. For this purpose, geoinformation technologies, field research, statistics, and chemical and chemical-analytical methods were used (automated spectrometric methods of segmented flow analysis, photocolorimetry, flame photometry, and inductively coupled plasma atomic emission spectrometry). During the first stage of this study, the bottom sediments of three lakes in the region, which were at different stages of eutrophication, were selected to study the chemical composition of the raw materials. The sapropel of Lake Penkovskoye had optimal indicators. Further, an analysis of the territory of the region for the development of agrotourism was carried out. The aim of this study is to substantiate the prospects for the use of sapropel in the production of innovative fertilizers. The natural origin of sapropels allows them to be used in the production of environmentally friendly and safe products. Reducing the use of artificially synthesized mineral fertilizers will make agriculture and the environment safe and sustainable. This will further contribute to the development of agrotourism in the region.

“…However, when discussing the sorption mechanism of organic molecules, the type and relative share of the pore types, particularly the meso- and micropores, is also significant. Recently, a modified β-cyclodextrin sorbent with greatly enhanced sorptive properties due to the formation of microspheres on the sorbent surface was designed (2023, [ 65 ]). In the modified biosorbent (BCd), the content of the micropores and mesopores with deashing increased 2.5 and 3.5 times, respectively.…”

Deashed Wheat-Straw Biochar as a Potential Superabsorbent for Pesticides

Biochar activation methods have attracted extensive attention due to their great role in improving sorptive properties of carbon-based materials. As a result, chemically modified biochars gained application potential in the purification of soil and water from xenobiotics. This paper describes changes in selected physicochemical properties of high-temperature wheat-straw biochar (BC) upon its deashing. On the pristine and chemically activated biochar (BCd) retention of five pesticides of endocrine disrupting activity (carbaryl, carbofuran, 2,4-D, MCPA and metolachlor) was studied. Deashing resulted in increased sorbent aromaticity and abundance in surface hydroxyl groups. BCd exhibited more developed meso- and microporosity and nearly triple the surface area of BC. Hydrophobic pesticides (metolachlor and carbamates) displayed comparably high (88–98%) and irreversible adsorption on both BCs, due to the pore filling, whereas the hydrophilic and ionic phenoxyacetic acids were weakly and reversibly sorbed on BC (7.3 and 39% of 2,4-D and MCPA dose introduced). Their removal from solution and hence retention on the deashed biochar was nearly total, due to the increased sorbent surface area and interactions of the agrochemicals with unclogged OH groups. The modified biochar has the potential to serve as a superabsorbent, immobilizing organic pollutant of diverse hydrophobicity from water and soil solution.

Soil plasticity characteristics are of great importance to practicing engineers and academics due to their wide range of applications mainly concerning settlement and soil strength assessment and volume change behavior. Therefore, assigning a plasticity value to soils under any discipline concerning soil engineering is critical. This is almost always carried out by determining plasticity index of soils in geotechnical engineering. However, overall plasticity characteristics of soils might not be reflected by using plasticity index alone. This research demonstrates the creation of a single model to define the plasticity potential of soils by using multivariate statistical techniques. Various soil properties including mineralogical features were integrated into the model. Some of these properties explained the soil plasticity positively and some of them negatively. The difference in plasticity characteristics of clayey soils were also identified. The model is created to be applied simply by using only two inputs for worldwide suitability. A single expression and two different scaled charts are proposed along with six ranges of plasticity potential for easy and broader application. This model proved that plasticity index alone needs refinement in practical applications.
