Removal of imidacloprid using activated carbon produced from ricinodendron heudelotii shells

Abstract

ABSTRACT. In this study, Ricinodendron heudelotii (akpi) shells are used as precursor to prepare activated carbon via chemical activation using phosphoric acid. The characterization of the obtained activated carbon is performed using X-ray diffraction (XRD), Boehm titration method and adsorption of acetic acid. The results show that the prepared activated carbon has a microstructure and a higher specific surface area (1179 m 2 /g), suggesting that the acid treatment has a significant positive influence on its sorption properties. The maximum adsorption capacity and pollutant elimination efficiency are found to be 43.48 mg/g and 90%, respectively. These results suggest that this low cost agent is an efficient tool to remove organic pollutants especially imidacloprid from wastewater.

Poly(β-cyclodextrin)-Activated Carbon Gel Composites for Removal of Pesticides from Water

“…For the sake of comparison, the values of RE and q m reported in the Table 1 for the removal of IMD by using AC [ 40 , 41 ] are lower than those obtained by us, and are similar to those corresponding to the use of PCD/AC 5% and PCD/AC 10% .…”

Identification of Active Species in Photodegradation of Aqueous Imidacloprid over g-C3N4/TiO2 Nanocomposites

“…Thus, the removal of these pollutants from water is essential due to their harmful influence on human health and aquatic ecosystems. Various methods can be applied for the degradation of IMI from aqueous solutions such as microfiltration membrane [11], biological degradation [12], adsorption [13,14], and advanced oxidation processes (AOPs) [15,16]. Among the AOP methods, photocatalytic activity has been used effectively in wastewater treatment for the removal of organic pollutants due to its simplicity, high activity, low cost, and ability to reduce CO 2 [17,18].…”

Optimization of Preparation Conditions of Activated Carbons Based on the Shells of <i>Ricinodendron heudoltii</i>

“…They can be obtained by carbonization and activation of a precursor already containing a large part of carbon and a low percentage of inorganic matter. Enough plant debris and animal bones have been used to produce activated charcoal [4]- [9]. Thus, coconut shells [4], cocoa pods [5], peanut shells [6], rice bran [7], chicken bones [8] and corn cobs [9] were used to produce activated carbon.…”
