The stability of an emulsified liquid membrane composed of Span80 as a surfactant, D2EHPA as an extractant and sulfuric acid as an internal phase was first studied according to different diluents and many operating parameters using the Plackett-Burman design of experiments. Then the removal of methylene blue from an aqueous solution has been carried out using this emulsified liquid membrane at ...

obtained without a phenol/chloroform extraction; however, fewer errors, greater signal strength and longer reads are obtained from the inclusion of a phenol/chloroform extraction before the butanol precipitation (Figure 1, A and C). In conclusion, this paper presents a simple dye terminator sequencing product purification protocol. This protocol is standardly used in our laboratory and provides...

Methanol extracts of onion peel waste (Allium cepa) were applied as natural sensitizer in Dye-Sensitized Solar Cell (DSSC) fabrication. This research investigated the dye characteristics extract and its power conversion efficiency. Onion extraction was carried out using unacidified methanol (UME) acidified (AME). Dye absorption characterized by UV-Vis Spectrophotometer at a wavelength 200-800 n...

Extraction and study of the optical properties natural dyes from several plant parts such as leaves, flowers, tubers, fruits have been carried out using a simple maceration method UV-Vis absorption characterization. The samples were divided into groups in this study, namely flower group (Tagetes sp., Paeonia Centaure Chrysanthemum Carthamus tinctorius, Gomphrena globosa, Myosotis sylvatica, Lav...

C-Phycocyanin is a natural blue dye used in food and pharmaceutical industry. In the present study, a simple and efficient method to extract C-phycocyanin from Spirulina platensis wet biomass is reported. The extractions were carried out using six different methods, including chemical (organic and inorganic acid treatment), physical (freezing and thawing, sonication, homogenization) and enzymat...

The removal of methyl orange dye, MO, has been accomplished through the use liquid-liquid extraction from aqueous solutions using Amberlite LA-2 as an extractant. UV-Vis spectroscopy was used to determine concentration dye in solution. effect pH studied at a specific and contact time. initial (20-80 ppm), (0.011-0.044 M) on rates different times (15- 60 min), temperatures 20-40 OC have investig...

The article elucidates the possibility of using yellow dye, obtained from saffron petals (Carthamus Tinctorius L.) in food industry. This powdered added to yoghurt concentrations 0.3 – 0.4%, addition its color, gives samples a light aroma flowers and demonstrates high stability during storage at 4° C. for 28 days. values chromatic coordinates, L *, b yogurt did not undergo considerable changes ...
