| Summary: | The growing concerns on the environment in recent years have influenced
the usage of renewable sources as alternative materials to create a platform for the
development of new technology with possible economic potential. Adsorbents
derived from agricultural wastes have hidden economic values which could be
benefited by transforming the agricultural wastes into valuable and useful products.
Numerous agricultural wastes such as skins/peels, cores, pits, leaves, brunches, and
pericarp are being produced in plantation and processing industries. The agricultural wastes have exhibited the potential usage as an adsorbent to remove contaminants
from water environment which conserve the natural environment and resources
mainly in the ecology system sustainably, for the reason that this utilization converts
the agricultural wastes into value-added product and at the same time decontaminate
polluted water source. This application on the utilization of agricultural wastes is not
only good for a sustainable environment but is also suitable for rural economic
development, meaning possible increases in profit for farmers and the agricultural
industry. This chapter provides insight on some findings on heavy metal removal by
adsorbents produced from agricultural wastes. The chapter also discusses the situation of the heavy metals in the environment, parameters affecting the adsorption
process of the heavy metals, kinetic models, and adsorption isotherms that are
associated with the agricultural waste-derived adsorbents. The development of the
adsorbents from agricultural waste biomass and the prospect of developing hybrid
adsorbent and magnetic adsorbent have attracted many researchers worldwide in
performing research work on the application to water and wastewater treatment. |
