【摘要】：基于環(huán)保背景和柔和"資源再生,循環(huán)經(jīng)濟(jì)"的理念,設(shè)計(jì)了化工工藝綜合實(shí)驗(yàn)——萃取流程對(duì)二壬基萘磺酸(DNNSA)反膠團(tuán)萃取鎂效率的影響。以DNNSA為萃取劑、磺化煤油為稀釋劑組成的反膠團(tuán)有機(jī)相,以冶金廢水為含鎂原料,首先測(cè)定冶金廢水中鎂離子含量,通過(guò)DNNSA對(duì)廢水中鎂萃取后測(cè)定萃余液鎂離子含量,由萃取前后鎂離子濃度計(jì)算得到萃取率�？疾炝藛渭�(jí)萃取、多級(jí)錯(cuò)流萃取、多級(jí)逆流萃取、連續(xù)接觸逆流萃取等工藝流程對(duì)萃取鎂效率的影響。該實(shí)驗(yàn)具有較好的設(shè)計(jì)性,拓展了學(xué)生的工程應(yīng)用視野,培養(yǎng)了學(xué)生探索問(wèn)題、發(fā)現(xiàn)問(wèn)題、研究問(wèn)題和解決問(wèn)題的能力。可作為應(yīng)用技術(shù)型本科院�；I(yè)的綜合性實(shí)驗(yàn)。
[Abstract]:Based on the background of environmental protection and the concept of "Resource Regeneration, Circular economy", the effect of chemical process comprehensive experiment-extraction process on magnesium extraction efficiency by DNNSA-DNSA-DNSA-DNSA-dinonylnaphthalenesulfonate reverse micelles was designed. Using DNNSA as extractant, sulfonated kerosene as diluent, and metallurgical wastewater as magnesium-containing raw material, the content of magnesium ion in metallurgical wastewater was first determined, and the content of magnesium ion in waste water was determined by DNNSA after extraction. The extraction rate was calculated by magnesium ion concentration before and after extraction. The effects of single-stage extraction, multi-stage cross-current extraction, multi-stage countercurrent extraction and continuous contact countercurrent extraction on the extraction efficiency of magnesium were investigated. The experiment has good design, broadens the students' application field of engineering, and cultivates the students' ability to explore, discover, study and solve problems. It can be used as a comprehensive experiment of chemical engineering major in applied technology colleges.
