中文摘要：

黄铁矿上的半胱氨酸的吸附机制被吸附的数量学习， FTIR 和 XRD 大小。吸附实验获得的结果建议那个著名计算机生产厂商他到半胱氨酸 m_p/m_c 的矿物质的集体比率比 5 大，在为与 m_p/m_c 吸附的 15 min 和半胱氨酸的吸附显示出一样的趋势以后，在矿物质 iss 上吸附的数量搁置。Itcan 被它化学相互作用管理的 Langmuir 类型等温吸附线推断全部吸附过程。从 FTIR 和 XRD 的结果证明半胱氨酸的官能基在 FTIR 光谱与他们的典型吸附山峰的蓝移动出现；同时，晶格常数显然减少并且拓宽水晶飞机例如(210 ) ，，并且((220 ) ，并且(211 ) 在半胱氨酸在矿物质上吸附以后被发现。

英文摘要：

The adsorption mechanism of cysteine on pyrite was studied by amounts adsorbed, FTIR and XRD measurements. The results obtained by adsorption experiment suggest that as the mass ratio of mineral to cysteine mp/mc is greater than 5, the amounts adsorbed on mineral is stable after adsorption for 15 min and cysteine adsorbing with mp/mc shows the same tendency. It can he inferred by its Langmuir-type adsorption isotherm that chemical interaction governs the entire adsorption process. The results from FTIR and XRD prove that the functional groups of cysteine appear with blue shift of their characteristic adsorption peak in FTIR spectrum; meanwhile, the lattice constant obviously decreases and the widening of crystal planes such as （210）, （220） and （211） is found after cysteine adsorbing on mineral.
