Abstract

Coriander powder, derived from the seeds of the Coriandrum sativum plant, represents a promising and eco-friendly solution
for pollutant removal from aqueous environments. This review paper aims to provide a thorough consolidation of recent
research on the utilization of coriander powder as an adsorbent for various contaminants. The scope of the review encompasses
its effectiveness in adsorbing a range of pollutants, including heavy metals, synthetic dyes, and organic contaminants. The
paper delves into the fundamental mechanisms of adsorption as they pertain to coriander powder. It examines the interaction
between the adsorbent and different types of pollutants, providing insights into how coriander powder facilitates the removal
process. The review also highlights key factors influencing the adsorption capacity of coriander powder, such as particle size,
pH, temperature, and contact time, and explores how these variables affect the efficiency of pollutant removal. In addition, the
review discusses potential modifications and treatments that can enhance the adsorption performance of coriander powder.
These modifications may include chemical treatments, physical alterations, or the development of composite materials.
The paper aims to identify and summarize the advancements in enhancing the adsorbent’s performance, thus providing
a comprehensive overview of current practices and future directions in the field. By consolidating findings from various
studies, this review provides valuable insights into the practical application of coriander powder in water treatment processes
and offers guidance for future research aimed at optimizing its use as a low-cost, sustainable adsorbent for environmental
remediation.
