摘　　要：以风化煤为原料,利用酸化和交联等反应进行交联改性,研制出一种新型海水净化剂。利用紫外分光光度计(UV)、傅里叶红外光谱仪(FTIR)、X-射线荧光光谱仪(XRF)等考察了新型海水净化剂的净化效果和化学结构。结果表明,经过化学改性后的风化煤稳定性提高,对海水中的金属离子和有机物有很好的吸附效果,提高了风化煤的使用价值。Weathered coal,the primary material,was first activated by strong acid. And then the crosslinking agent and assistant were used to cross-link it and changed its property. Finally,the new-type seawater cleaning agent was prepared. And the purifying effect of this new-type agents and its chemical structure were respectively investigated by ultraviolet and visible spectrophotometry（ UV）,fourier transform infrared spectrometer（ FTIR）,and X-ray fluorescence（ XRF）. The result showed that the stability of weathered coal with property change via chemical method was enhanced and its absorbing effect on metal cations and organic matters in new-type seawater was improved significantly,all of which improved the use value of weathered coal.
