The relationship between extraction distribution ratio D and sodium sulfate,sodium chloride and sodium nitrate were examined. It is found that the D of succinic acid increases with the increasing of the concentrations of salts and the order of the salting - out effects is sodium nitrate > sodium chloride > sodium; the D of citric acids decreases at first, and then increases, and the order of the salting - out effects is the same as the succinic acid. The empirical formula of salting-out effect is obtained based on the experimental data.</em></p><p class='subject'><strong>关 键 词：</strong><a href='/subject/article.aspx?id=4581899' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e7%bb%9c%e5%90%88%e8%90%83%e5%8f%96%5d' title='络合萃取'>络合萃取</a> <a href='/subject/article.aspx?id=360170' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e4%b8%81%e4%ba%8c%e9%85%b8%5d' title='丁二酸'>丁二酸</a> <a href='/zk/search.aspx?key=K%3d%5b%e6%9f%a0%e6%aa%ac%e9%85%b8%5d' title='柠檬酸'>柠檬酸</a> <a href='/zk/search.aspx?key=K%3d%5b%e4%b8%89%e7%83%b7%e5%9f%ba%e8%83%ba%5d' title='三烷基胺'>三烷基胺</a> <a href='/subject/article.aspx?id=796301' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e7%9b%90%e6%9e%90%e5%89%82%5d' title='盐析剂'>盐析剂</a> </p><p class='class'><strong>分 类 号：</strong><a href='/zk/search.aspx?key=C%3dO652.62' title='O652.62'>O652.62</a>[<a href = '/domain/article.aspx?id=411' >理学—分析化学</a>] </p> </div> <div id="content_wzxg" name="wzxg" class="article-graph"> <object width="695" height="250" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" id="FlashID"> <param value="../flash/relation.swf" name="movie"> <param value="high" name="quality"> <param value="opaque" name="wmode"> <param value="6.0.65.0" name="swfversion"> <param value="dataUrl=/ajax/articlerelativegraph.ashx?id=10846143" name="flashVars"> <embed width="695" height="250" src="../flash/relation.swf" type="application/x-shockwave-flash" quality="high" wmode="opaque" flashvars="dataUrl=/ajax/articlerelativegraph.ashx?id=10846143"> </embed> </object> </div> <div class="article-relate-list"> <div class="relate-list"> <p id="ckwx_br"> </p> <h2 name="ckwx" id="ckwx">参考文献：</h2> <div id="listckwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="2jckwx_br"> </p> <h2 name="2jckwx" id="2jckwx">二级参考文献：</h2> <div id="list2jckwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="ohwx_br"> </p> <h2 name="ohwx" id="ohwx">耦合文献：</h2> <div id="listohwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="yzwx_br"> </p> <h2 name="yzwx" id="yzwx">引证文献：</h2> <div id="listyzwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="2jyzwx_br"> </p> <h2 name="2jyzwx" id="2jyzwx">二级引证文献：</h2> <div id="list2jyzwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="tbywx_br"> </p> <h2 name="tbywx" id="tbywx">同被引文献：</h2> <div id="listtbywx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="xgqklw_br"> </p> <h2 name="xgqklw" id="xgqklw">相关期刊文献：</h2> <div id="listxgqklw"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> </div> </div> <div class="article-about"> <div class="about-box"> <h5 class="name">相关的主题<tt><a class="hide" href="#"></a></tt></h5> <div class="about-list"> </div> </div> <div class="about-box"> <h5 class="name">相关的作者对象<tt><a class="" href="#"></a></tt></h5> <div class="about-list" style="display: none;"> </div> </div> <div class="about-box"> <h5 class="name">相关的机构对象<tt><a class="" href="#"></a></tt></h5> <div class="about-list" style="display: none;"> </div> </div> </div> </div> </div> <script type="text/javascript" src="/scripts/articlerelation.min.js"></script> <script type="text/javascript" src="/scripts/articlerightrelation.min.js"></script> <script type="text/javascript" src="/scripts/articledown.min.js"></script> <div class="layer-box download" id="downloadlayer" style="display: none"> <div class="close"> <a onclick="closedown()" href="javascript:void(0)"> <img src="/images/layer-close.png" width="21" height="21" alt="" /> </a> </div> <h5 class="layer-title">下载全文</h5> <div id="downloadinfo"></div> </div> <div class="layer-box download" id="downloadlayer2" style="display:none;min-height:100px;width:500px;"> <p> <img src="/images/loading2.gif" width="64" height="64"> <span style="font-size:20px;vertical-align:middle;padding-bottom:50px;">正在链接到云南高校图书馆文献保障联盟下载...</span> </p> </div> <script id="bdshare_js" data="type=tools&uid=0" type="text/javascript"></script> <script type="text/javascript"> $(function () { var rd = GetQueryString("rd");
