靛酚蓝法测定海水、河口水中铵氮的“盐效应”及其消除

靛酚蓝法是国际上测定海水、河口水中铵氮(nH4-n)最常用的方法之一,但“盐效应“问题严重影响nH4-n测定的数据质量,需要将反应体系调整到最佳PH值,即:10.5。该文报道一种方法,依据样品盐度添加适量nAOH试剂来调节PH值到最佳,从而方便地解决靛酚蓝法测定咸水中nH4-n的“盐效应“问题,并通过真实样品的加标回收实验证明该方法的确有效。在光程为5CM时,该方法的检出限为0.03μMOl/l,线性范围为0.2~8μMOl/l,真实样品的加标回收率为96.9%~108.8%

Chlorinated stabilization, hydrogenation and oxidation upon fused-pentagon fullerenes (C50, C56, C60)

自1985年C60被发现以来，富勒烯的研究取得了长足的进步，尽管在此期间发现了很多富勒烯的新成员，独特的结构和物化性质也都表明其在生活和科研的各个方面都有着广泛的应用前景，然而目前真正得到商业化的仅有包括C60在内有限的几种，这主要是因为大多数富勒烯结构中相邻五元环的存在，违背了IPR(IsolatedPentagonRule)规则，因而十分活泼，难以被捕获，此类富勒烯即非IPR富勒烯。富勒烯研究的重点之一即非IPR富勒烯的稳定化。理论研究表明许多富勒烯的非IPR异构体可能是稳定富勒烯形成的中间体，因而对于富勒烯形成机理的探索不可或缺。通过对这些活泼富勒烯的捕获，从实验上揭开这些神秘大分子的结...Since the discovery of fullerene C60 in 1985, studies on fullerenes have achieved progress on a wide range of research fields. In spite of many new members in this huge family being discovered and their potential in a variety of applications owing to their unique cagey structure and physicochemical properties, only C60 is used commercially in addition to a few of larger fullerenes such as C70.
