The reaction order and the apparent activation energy have been determined. A new method for the determination of Cu has been set up. The limit of detection is 6.1×10-3 μg/mL of Cu and the linear range is 0～4.0 μg/25 mL of Cu. The method has been used to determine trace Cu in human hair with the results corresponding to that determined by AAS.</em></p><p class='subject'><strong>关 键 词：</strong><a href='/subject/article.aspx?id=2465409' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e9%85%b8%e6%80%a7%e5%a4%a7%e7%ba%a2%5d' title='酸性大红'>酸性大红</a> <a href='/subject/article.aspx?id=2735657' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e8%a4%aa%e8%89%b2%e5%85%89%e5%ba%a6%e6%b3%95%5d' title='褪色光度法'>褪色光度法</a> <a href='/zk/search.aspx?key=K%3d%5b%e6%b5%8b%e5%ae%9a%5d' title='测定'>测定</a> <a href='/subject/article.aspx?id=8082851' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e9%93%9c%5d' title='铜'>铜</a> <a href='/subject/article.aspx?id=6478225' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e7%97%95%e9%87%8f%e5%88%86%e6%9e%90%5d' title='痕量分析'>痕量分析</a> </p><p class='class'><strong>分 类 号：</strong><a href='/zk/search.aspx?key=C%3dO614.121' title='O614.121'>O614.121</a>[<a href = '/domain/article.aspx?id=407' >理学—无机化学</a>] <a href='/zk/search.aspx?key=C%3dO657.32' title='O657.32'>O657.32</a>[<a href = '/domain/article.aspx?id=406' >理学—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=6607360" 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=6607360"> </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");
