Abstract

This article a synthesis of humic acid with the obtaining of potassium humate based on coal waste from the Lenger deposit. Accumulated industrial waste heavily pollutes the environment and has a direct impact on all living things. The accumulation of waste in landfills increases the pollution level of the atmosphere, soil, groundwater, and surface water, destroys the functioning of ecosystems, and damages agriculture and construction. A sieve analysis was carried out to study the fine fractions of coal waste, and a scanning electron microscope analysis was performed to study the mineralogical, structural state and X-ray chemical phase composition. The chemical composition of coal waste was studied using differential thermal analysis during heat treatment. The optimal parameters of the process for obtaining humic acids are established, and the results of experimental work are presented. The results are confirmed by mathematical planning of the experiment using the method of orthogonal plan of the second order. The mathematical planning results were tested according to the Student and Fischer criteria. Based on the conducted studies, it was identified that the degree of extraction of humic acid reaches up to 95.90% in terms of the organic phase, and the concentration of humic acid is 49.13%. From the humic acids obtained using potassium hydroxide, potassium humate was synthesized. The potassium humate obtained in its composition has fertilizer properties. Therefore, the obtained potassium humate will be used for the production of humic fertilizers to improve soil fertility and crop yields. The synthesis of humic acids with the production of potassium humate is aimed at reducing the accumulated industrial waste, which in turn allows you to regulate and improve the ecological situation and green ecology in the region.

利用哈萨克斯坦伦格矿床的煤炭废料合成腐殖酸并获得腐殖酸钾

本文以伦格矿床的煤炭废料为基础，合成腐植酸并获得腐植酸钾。累积的工业废物严重污染环境，并对所有生物产生直接影响。垃圾在垃圾填埋场的堆积增加了大气、土壤、地下水和地表水的污染程度，破坏了生态系统的功能，损害了农业和建筑业。通过筛分分析研究了煤炭废物的细小组分，并通过扫描电子显微镜分析研究了矿物学、结构状态和 X 射线化学相组成。在热处理过程中，使用差热分析研究了煤废料的化学成分。确定了获得腐殖酸的最佳工艺参数，并介绍了实验结果。使用二阶正交规划法对实验进行数学规划，从而确认了实验结果。根据学生标准和费舍尔标准对数学规划结果进行了检验。根据研究结果，腐植酸在有机相中的提取率达到 95.90%，腐植酸浓度为 49.13%。利用氢氧化钾提取的腐植酸合成了腐植酸钾。得到的腐植酸钾具有肥料特性。因此，获得的腐植酸钾将用于生产腐植酸肥料，以提高土壤肥力和作物产量。用生产腐植酸钾的方法合成腐植酸，旨在减少累积的工业废物，从而调节和改善该地区的生态状况和绿色生态。

期刊介绍： Green Processing and Synthesis is a bimonthly, peer-reviewed journal that provides up-to-date research both on fundamental as well as applied aspects of innovative green process development and chemical synthesis, giving an appropriate share to industrial views. The contributions are cutting edge, high-impact, authoritative, and provide both pros and cons of potential technologies. Green Processing and Synthesis provides a platform for scientists and engineers, especially chemists and chemical engineers, but is also open for interdisciplinary research from other areas such as physics, materials science, or catalysis.
