【摘要】：基于環(huán)保背景和柔和"資源再生,循環(huán)經(jīng)濟"的理念,設(shè)計了化工工藝綜合實驗——萃取流程對二壬基萘磺酸(DNNSA)反膠團萃取鎂效率的影響。以DNNSA為萃取劑、磺化煤油為稀釋劑組成的反膠團有機相,以冶金廢水為含鎂原料,首先測定冶金廢水中鎂離子含量,通過DNNSA對廢水中鎂萃取后測定萃余液鎂離子含量,由萃取前后鎂離子濃度計算得到萃取率�？疾炝藛渭壿腿�、多級錯流萃取、多級逆流萃取、連續(xù)接觸逆流萃取等工藝流程對萃取鎂效率的影響。該實驗具有較好的設(shè)計性,拓展了學生的工程應用視野,培養(yǎng)了學生探索問題、發(fā)現(xiàn)問題、研究問題和解決問題的能力。可作為應用技術(shù)型本科院�；I(yè)的綜合性實驗。
[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.
