, 2005 研究了酸碱2步改性对活性炭吸附水相中Cr（Ⅵ）的影响.将活性炭（AC0）在HNO3溶液中氧化（AC1）,然后在NaOH和NaCl的混合液中处理（AC2）.分别采用平衡和连续吸附试验,测试Cr（Ⅵ）的吸附特征.以Boemh滴定法定量检测活性炭表面酸性官能团数量,结合元素分析结果定量表征活性炭的表面含氧官能团变化;以低温液氮（N2/77K）吸附法分析活性炭的比表面积和孔径结构.结果表明：活性炭经2步改性后,其Cr（Ⅵ）的吸附容量和吸附速度均显著改变.吸附容量和吸附速度大小依次为AC2＞AC1＞AC0 ...

The effects of inorganic anions and Fe(Ⅲ) on Cr(Ⅵ) photoreduction in a solution with different pH
, 2014 鉻的用途隨著工業發展及人類生活水準的提高而日益增加，相對地，鉻污染環境的可能性也隨其用途的增加而加劇。鉻在水體中通常以三價鉻和六價鉻兩種形態存在，兩者的物化特性和毒性相差甚大。Cr(Ⅲ)與固體粒子具高反應性，可直接沈澱或吸附在懸浮粒子上，形成難溶之氫氧化物，移動性低故溶液中Cr(Ⅲ)濃度較低，一般而言對環境危害不大；反之，Cr(Ⅵ)溶解度大，移動性高，且毒性較Cr(Ⅲ)強(約高300倍)。因此，根據化學行為和毒性間的差異，多半將環境中之Cr(Ⅵ)還原成Cr(Ⅲ)來降低其危害風險。 許多研究已證實，

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Hereditary Spastic Paraplegia (HSP) comprises a group of rare genetic diseases characterized by length‐dependent axonal degeneration of the corticospinal tracts and dorsal columns, whose main clinical feature is spastic gait. Pathogenic variants in the SPG4 gene cause Spastic Paraplegia Type 4 (SPG4‐HSP), the most common form of HSP.
