Cloud Point Extraction and Spectrophotometric Determination of Allura Red (E129) in Foodstuffs

Selective Cloud Point Extraction for the Spectrophotometric Determination of Cetylpyridinium Chloride in Pharmaceutical Formulations

In this work, we developed a simple and selective method for separation and spectrophotometric determination of trace amounts of cetylpyridinium chloride (CPC) in pharmaceutical products using cloud point extraction (CPE) technique. The method is based on cloud point extraction of the CPC in alkali conditions using of nonionic surfactant Triton X-114. Under selected conditions, the calibration ...

Extraction, Analytical and Advanced Methods for Detection of Allura Red AC (E129) in Food and Beverages Products

Allura Red AC (E129) is an azo dye that widely used in drinks, juices, bakery, meat, and sweets products. High consumption of Allura Red has claimed an adverse effects of human health including allergies, food intolerance, cancer, multiple sclerosis, attention deficit hyperactivity disorder, brain damage, nausea, cardiac disease and asthma due to the reaction of aromatic azo compounds (R = R' =...

spectrophotometric determination of molybdenum in pharmaceutical samples and blood plasma after cloud point extraction

cloud point extraction and spectrophotometric determination of cadmium in some vegetables

cloud point extraction and spectrophotometric determination of trace quantities of cadmium in some vegetables have been developed. the research area for vegetables analysis was near to the zarin shahr where the soil received heavy metals from the esfahan steel company. cloud point extraction used dithizone as complexing agent and non ionic surfactant triton-x114 as micellar phase. several impor...
