8.4.1 Agricultural Waste as Low-Cost Adsorbents
The idea of using various agricultural waste materials for the remediation of heavy
metal from water has been explored in number of studies (Bhatnagar and Sillanpää
2010; Bilal et al. 2013; Farooq et al. 2010). Scientists examined the effectiveness of
different organic waste products as sorbents for heavy metals. The major plus point
of this strategy in contrast with others is lower cost when natural waste materials are
utilized. Due to these benefits, the utilization of different waste products for metal
remediation from wastewater has been highlighted. These waste materials ranged
from industrial materials and natural waste materials such as agricultural product
and by-product (Inyang et al. 2016; Tripathi and Ranjan 2015).
Agricultural products and by-products is an abundant waste material, and needs
to be disposed of properly. There are different methods that can be used for agricultural waste disposal, among them in situ burning is mostly used which produces
CO 2 and some other toxicants, thus are harmful for environment. This motivates the
alteration of agricultural waste and by-products into beneficial and value-added
products. One promising solution is to use this waste as low-cost ion exchange or
