Adsorption of Rhodamine B from AqueousSolution by Goat Manure Biochar: Kinetics,Isotherms, and Thermodynamic Studies

Rhodamine B (RhB) is a synthetic organic dye widely used in textile, paper-making, leather manufacture, stained glasswork, the cosmetics industry and many other industries due to its high tinting strength, bright color and high stability [1,2].These industries produce a great amount of RhB dye wastewater, with the characteristics of high colority, poor biodegradability and heavy toxicity [3].The traditional biological method hardly meets the emission requirements, while directly draining into water would cause serious threats to the environment and human health.Previous experimental studies have
