Гуминовые вещества (ГВ) – это разнообразный класс природных соединений без фиксированного химического состава, образующихся из растительных и микробных остатков под действием факторов окружающей среды и живых организмов в течение многих лет. Несмотря на обширные исследования, продолжавшиеся два столетия, сложный и изменчивый характер структуры ГВ остается предметом научных исследований. Эти вещества, особенно гуминовые кислоты, фульвокислоты и гумин, играют решающую роль в экологических и экологических процессах из-за их большого количества функциональных групп и устойчивости к биоразложению. В обзоре рассматриваются сложная структура и свойства ГВ, их классификация и распространение в природе. В нем освещаются различные модели, предложенные для описания структурных фрагментов гуминовых кислот, подчеркиваются их ароматические ядра и разнообразные функциональные группы. Обсуждается также изменчивость молекулярно-массового распределения ГВ, обусловленная их полидисперсной природой, а также методы их определения, такие как эксклюзионная хроматография. Кроме того, изучен элементный и функциональный состав гуминовых кислот, уточнены их кислотно-основные свойства и способность к комплексообразованию тяжелых металлов. Освещается синтез ГВ из природных источников, таких как почва, торф, уголь, а также искусственных процессов, демонстрируя такие методы, как щелочная экстракция и гидротермальная обработка. Последние достижения в области искусственной гумификации, включая окислительный аммонолиз и окисление на основе реагента Фентона, рассматриваются на предмет их потенциала в производстве экологически чистых гуминовых материалов из лигнина и биомассы отходов. В заключение исследования подчеркивается экологическая значимость и практическое применение ГВ, особенно в сельском хозяйстве, кондиционировании почвы и восстановлении окружающей среды. Разнообразные свойства и методы синтеза ГВ делают их перспективными кандидатами для устойчивого производства материалов и управления окружающей средой.

Humic substances (HSs) are a diverse class of natural compounds with no fixed chemical composition, formed from plant and microbial residues through the action of environmental factors and living organisms over many years. Despite extensive research spanning two centuries, the complex and variable nature of HSs' structure remains a subject of scientific inquiry. These substances, notably humic acids, fulvic acids, and humin, play crucial roles in ecological and environmental processes due to their abundant functional groups and resilience to biodegradation. This review explores the intricate structure and properties of HSs, their classification, and their occurrence in nature. It highlights the different models proposed to describe the structural fragments of humic acids, emphasizing their aromatic cores and diverse functional groups. The variability in the molecular weight distribution of HSs, attributed to their polydisperse nature, is also discussed, along with methods used for their determination, such as exclusion chromatography. Furthermore, the elemental and functional compositions of humic acids are examined, detailing their acid-base properties and capacity for heavy metal complexation. The synthesis of HSs from natural sources, such as soil, peat, coal, and artificial processes, is covered, showcasing methods like alkaline extraction and hydrothermal treatment. Recent advancements in artificial humification, including oxidative ammonolysis and Fenton reagent-based oxidation, are reviewed for their potential in producing environmentally friendly humic materials from lignin and waste biomass. The study concludes by underscoring the environmental significance and practical applications of HSs, particularly in agriculture, soil conditioning, and environmental remediation. The diverse properties and synthesis methods of HSs make them promising candidates for sustainable material production and environmental management. Humic acids are versatile compounds beneficial for human health due to their potent antioxidant properties, immune-modulating effects, and support for gastrointestinal health and detoxification. Structurally diverse, they feature groups like carboxyl, phenolic hydroxyl, quinones, ketonic carbonyls, amino, and sulfhydryl, contributing to their stability and amphiphilic nature. In pharmaceutical applications, they show promise for drug delivery, antioxidant therapies, wound healing, antimicrobial actions, and biofilm disruption, underlining their biocompatibility and safety.
