Coal mining operations produce large amounts of tailings which contains heavy metals. Heavy metals such as cadmium (Cd) can cause environmental problems. The adsorption capacities of biochars produced from spent coffee beans and brewery waste were explored for the removal of Cd from single and multi-component solutions. The biochars were prepared by hydrothermal liquefaction (HTL) and characterized by scanning electron microscope analysis (SEM) and Fourier transform infrared microscopy (FTIR).doi:10.17758/eares4.eap1118230 fatcat:6gkd6ddzpzgxhbcpzs6lpobc2a
