摘要：

Wastewater disposal from beryllium production has become a significant problem in the industry. Therefore, this paper designed porous calcium carbonate biochar (CC-LBC) using Na2CO3 and CaCl2 to modify the biochar innovatively, after which we understudied the Be(II) adsorption effect of CC-LBC at different concentrations. The results from Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray Photoelectron Spectroscopy (XPS), and other characterization analyses showed that when CC-LBC particles were immersed i...
