摘要

Abstract <section xml:id="jctb5479-sec-0001" numbered="no"> <title type="main">BACKGROUND > The alginate extraction residue from Brazilian <fc> <fi>Sargassum filipendula</fi> </fc> was employed as biosorbent for Zn(II) removal through a fixed‐bed column in order to explore its adsorptive properties and to establish a new use for this waste. </section> <section xml:id="jctb5479-sec-0002" numbered="no"> <title type="main">RESULTS > The best operating conditions were 0.5 mL min ‐1 and 1.0 mmol L ‐1 (inlet concentration), providing lower mass transfer zone and higher uptake. Elution percentages of 52 and 73% were obtained for the first and second desorption cycles, respectively, using CaCl <sub>2</sub> as eluent. The Yan <fi>et al.</fi> model was more representative of the experimental data. Characterization revealed that ion exchange is involved between zinc ions and light metals (Ca, Na, K and Mg). A decrease was observed in real and apparent densities of biomass, with an increase in particle porosity of the residue after process. </section> <section xml:id="jctb5479-sec-0003" numbered="no"> <title type="main">CONCLUSION >The study revealed that this biomass has potential for Zn removal from aqueous solution, encouraging its application as a biosorbent in future studies involving multicomponent systems. ? 2017 Society of Chemical Industry </section> </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”> <title type =“main”>抽象</ title> <section XML：ID =“JCTB5479-SEC-0001 “编号=”否“> <标题类型=”main“>背景</ title> >来自巴西<fc> <fi> sargassum filipenduara </ fi> </ fc>的藻酸盐提取残余物作为生物吸附剂Zn（II）通过固定床柱去除，以探索其吸附性能，并为此废物建立新用途。 </ p> </ section> <section XML：ID =“JCTB5479-SEC-0002”编号=“否”> <标题类型=“main”>结果</标题> >最佳操作条件为0.5 ml最小 -1 </ sup>和1.0mmol l -1 </ sup>（入口浓度），提供较低的传质区和更高的摄取。使用CaCl <sub> 2 / sub作为洗脱剂，分别为第一和第二解吸循环获得52和73％的洗脱百分比。 Yan <Fi>等人。</ Fi>模型更像是实验数据的代表性。表征揭示了离子交换涉及锌离子和光金属（Ca，Na，K和Mg）。在生物质的实际和表观密度中观察到降低，并在过程后残留物的粒子孔隙率增加。 </ p> </ section> <部分XML：ID =“JCTB5479-SEC-0003”编号=“否”> <标题类型=“main”>结论</ title> >该研究显示这种生物质具有从水溶液中除去Zn的可能性，促进其作为生物吸附剂的应用，涉及多组分系统的未来研究。还2017年化学工业协会</ p> </段> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-33908/'>《Journal of Chemical Technology & Biotechnology》</a> <b style="margin: 0 2px;">|</b><span>2018年第4期</span><b style="margin: 0 2px;">|</b><span>共7页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Cardoso Saulo Luiz&option=202" target="_blank" rel="nofollow">Cardoso Saulo Luiz;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Costa Camila Stefanne Dias&option=202" target="_blank" rel="nofollow">Costa Camila Stefanne Dias;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=da Silva Meuris Gurgel Carlos&option=202" target="_blank" rel="nofollow">da Silva Meuris Gurgel Carlos;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Vieira Melissa Gurgel Adeodato&option=202" target="_blank" rel="nofollow">Vieira Melissa Gurgel Adeodato;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>School of Chemical Engineering University of CampinasCidade Universitária Zeferino VazCampinas SP Brazil;</p> <p>School of Chemical Engineering University of CampinasCidade Universitária Zeferino VazCampinas SP Brazil;</p> <p>School of Chemical Engineering University of CampinasCidade Universitária Zeferino VazCampinas SP Brazil;</p> <p>School of Chemical Engineering University of CampinasCidade Universitária Zeferino VazCampinas SP Brazil;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/180.html" title="生物工程学（生物技术）">生物工程学（生物技术）;</a><a href="https://www.zhangqiaokeyan.com/clc/20827.html" title="生物化学过程">生物化学过程;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=biosorption&option=203" rel="nofollow">biosorption;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=heavy metals&option=203" rel="nofollow">heavy metals;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=algae&option=203" rel="nofollow">algae;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=wastewater treatment&option=203" rel="nofollow">wastewater treatment;</a> </p> <div class="translation"> 机译：生物吸附;重金属;藻类;废水处理;
