that ethylenediamine (EDTA), triethanolamine (IPA), pyrazine and hydrazine, have caused reduction in etching rates[62, 66]. These organic compounds probably have a little coordinating action. When......
Trans. Nonferrous Met. Soc. China 29(2019) 876-892 Synthesis, in-situ coating and characterization of scorodite with high leaching stability Ping-chao KE, Zhi-hong LIU School of Metallurgy and Environment, Central South University, Changsha 410083, China Received 10 April 2018; accepted 24 October 2......
hydrolysable metal cations like Fe3+ and Al3+ of high concentrations. In such cases, complexing agents like EDTA, DCTA, their calcium and magnesium salts or reduction of Fe3+ to Fe2+ with potassium iodide......

= 410.68[76].Mohammadi等采用1L三己基(十烷基四)膦酸酯萃取硝酸浸出液中稀土,以EDTA选择性络合分离Nd,Dy,在最优参数条件下,最终制备的Nd2O3和Dy2O3纯度分别为99.6%和99.8%[77].溶剂萃取剂法虽然能生产单一稀土元素的产品,但在萃取过程中,萃取剂自身具有一定毒性,且易受到杂质离子影响而产生乳化现象,阻碍连续生产等弊端. 针对传统萃取剂的问题,离子液体萃......
是界面工程,尤其是钙钛矿与电子传输层之间的界面.BU等[46]在SnO2电子传输层表面旋涂氢氧化钾(KOH)溶液,K+与钙钛矿中的Br-结合成KBr,钝化界面缺陷,提升电池性能,同时消除了迟滞现象.YANG等[60]利用乙二胺四乙酸(EDTA)修饰SnO2电子传输层,处理过后E-SnO2表面更加亲水,降低了钙钛矿异质结成核的吉布斯自由能从而得到大晶粒,质量更高的钙钛矿薄膜,E-SnO2的电子迁移率......
