South Carolina produced the first kaolin mines in the United States. Today it contains some of the most productive clay beds in the United States, second only to neighboring Georgia. The predominant clay region in South Carolina follows the trend of the Sandhills across the upper coastal plain, with major production centered in Aiken County […]
A magnetic adsorbent based on chitosan–kaolin (Cs-k-Fe3O4) nanocomposite was synthesized by a one-pot co-precipitation method. The nanocomposite was used as an adsorbent in magnetic solid-phase extraction of tetracycline (TC) in wastewater and surface water. The Cs-k-Fe3O4 nanocomposite was characterized by the Fourier …
