Area of Science:
- Environmental Biotechnology
- Environmental Chemistry
- Materials Science
Background:
- Aerobic granular sludge represents a novel microbial aggregation technology for wastewater treatment.
- Its application as a biosorbent for diverse pollutants is an emerging research area.
Purpose of the Study:
- To provide a comprehensive review of aerobic granules as biosorbents.
- To analyze their effectiveness in removing heavy metals, nuclides, dyes, and inorganic substances.
Main Methods:
- Systematic review of existing literature on aerobic granules as biosorbents.
- Comparison of different granule types (intact, fragmented, modified) and their adsorption characteristics.
- Analysis of adsorption test conditions, performance data, and pollutant-granule interactions.
Main Results:
- Original aerobic granules are highly effective for cationic metals.
- Surface modification broadens applicability to oxyanionic metals, dyes, and other pollutants.

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
