Separation of Formic Acid from Aqueous Solutions by Liquid Extraction Technique at Different Temperatures

In this study, the separation of formic acid from aqueous solutions was investigated. Liquid-liquid equilibrium (LLE) data including tie-lines was reported for water + formic acid + 2-methylpropyl ethanoate ternary mixture at (293.15 to 323.15) K and atmospheric pressure. The system shows type-I phase behavior based on Treybal’s classification because only one partially miscible binary mixture ...

study of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives

برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...
