the genus haplophyllum, which belongs to the rutaceae family, includes 18 species in iran. in this study, after collecting plant material, botanical identification and suitable drying, the essential oils from aerial parts of haplophyllum robustum bge. were extracted by three different isolation techniques, conventional hydrodistillation (hd), microwave-assisted hydrodistillation (mahd) and solv...

A simple and reproducible method for the rapid extraction and determination of trace amounts of copper (II) ions using octadecyl-bonded silica membrane disks modified by Functionalized Graphene with octadecylamine (ODA–GO) and Atomic Absorption Spectrometry is presented. The method is based on complex formation on the surface of the ENVI-18 DISK TM disks followed by stripping of the retained sp...

a comparative study of ultrasound-assisted extraction (uae) and hydro-distillation was performed for fast extraction of estragole from tarragon (artemisia dracunculus l.) dried leaves. several influential parameters of the uae procedure in the extraction of estragole (type of solvent, extraction cycles, solvent to material ratio, irradiation time and particle size) were investigated and optimiz...

Tin anode slime is a by-product of the tin electrolytic refining process. This study investigated route to separate Sn, Sb, Bi, and Cu from after leaching with hydrochloric acid. In solvent extraction process tributyl phosphate, Sb Sn were extracted into organic phase. Bi unextracted remained in liquid stripping experiment, stripped separated HCl HNO3. aqueous phase also chemical precipitation ...

in this research, process asymmetric polyetherimide hollow fiber membranes using ethanol (0, 2 and 4 wt%) as non-solvent additive in the polymer dope via phase inversion method were fabricated. aqueous solution of 1-methyl-2-pyrrolidine (nmp) (90%) was applied as a bore fluid to avoid inner skin layer formation and water was used as the external coagulant. the morphology of fabricated membranes...

The present article includes the Ultrasound-Assisted Extraction (UAE) of Citrus unsiu Marc. leaves rich in polyphenols. The best possible combinations of solvent, pH of the media, solvent/solid ratio, extraction time, extraction temperature and particle size were obtained for the maximum extraction of Total Phenolic Compounds (TPC) and Total Flavonoid Compounds (TFC) by us...
