We assessed the impacts of different rates of biochar application (20, 40, 60 t ha-1) to peanuts grown in a loamy sand soil in the North China...
A response surface optimization based on ionic liquid dispersive liquid phase microextraction was developed for analysis of the endocrine disrupting compounds bisphenol A and 4-nonylphenol in water samples. The volume of the extraction solvent, volume of dispersive solvent, and pH were found to have significant effects on the response. Analysis of variance indicated that the model was significant...
