The spherical macroporous cellulose(SMC) was fabricated using medical absorbent cotton as raw material and nano CaCO3 as porogenic agents.And then,the phenylglycine was grafted onto the SMC to obtain the novel spherical macroporous cellulose derivative adsorbent(PSMC).FT-IR and scanning electron microscope(SEM) were employed to characterize the adsorbents and Fe3+ ions served as model solute to evaluate the adsorption property of the adsorbents.The experimental results show that the amount of porogenic agents and the value of pH have obvious influence on adsorption capacity of the adsorbents.The data of adsorption kinetic and isotherm display that the adsorbents possess excellent equilibrium adsorption capacity(348.94 mg/g) and have a bright prospect and considerable potential in the treatment of Fe3+ ions in wastewater. 相似文献

基于琼斯偏振理论,对通信系统光端机和大气传输信道进行了偏振建模,定量分析了传输过程中二者对信号光的偏振改变作用,并推导出信号光和本振光的偏振失配与混频效率之间的关系.在此基础上,利用偏振调控反馈算法和PCD-M02型压电陶瓷式偏振控制器(PCD),提出了一种自动反馈式偏振调控补偿装置,能够有效避免偏振失配现象的发生,保证了较高的混频效率,进而提高了空间相干光通信系统的整体性能. 相似文献
