Purification and Fractionation of Carbon Dots using pH-controlled Cloud Point Extraction Technique
In this work, we describe a simple, green and general procedure for the purification and fractionation of carbon dots (CDs). CDs coated with oxygen-containing functional groups were synthesized by thermal pyrolysis of citric acid. The product of the reaction was first Purified and then fractionated into two distinct kinds of CDs (f4 and f1) using pH-controlled cloud point extraction (CPE) techn...
متن کاملSimultaneous determination of Tropaeolin O and brilliant blue in food samples after cloud point extraction
In this study, a simple and low-cost method was developed for extraction and pre-concentration of brilliant blue(BB) and Tropaeolin O(TO) in food samples using cloud point extraction (CPE) prior to spectrophotometric determination. The effects of main factors such as pH, surfactant and salt concentrations, incubation time and temperature on the cloud point extraction of both dyes were investiga...
متن کاملA Green Enrichment Method of Copper, Manganese and Nickel in Water Samples via Cloud Point Extraction
A new, cost-effective, and environmental-friendly cloud point extraction methodology was described for enrichment of copper, manganese and nickel in several water samples. The method involves the complexation of copper, manganese or nickel with 2-amino-6-(1,3-thiazol-2-diazeyl)-phenol at pH 7.0, then extraction into Triton X-114. After dilution of the surfactant-rich phase with acidified methan...
متن کاملCloud Point Extraction of Pesticide Residues
Pesticides including organochlorine pesticides (OCPs), organophosphorus pesticides (OPPs), and nitrogen-containing herbicides are types of well-known environmental contaminants. Pesticides are generally categorized based upon their persistence in the environment. Organochlorine pesticides are considered persistent pesticides. These pesticides have long environmental half-lives and tend to bioac...
متن کاملSimultaneous Determination of Carbazoles in Water Samples by Cloud Point Extraction Coupled to HPLC
Cloud point extraction (CPE) as a rapid, simple and efficient method coupled with high performance liquid chromatography (HPLC) was used for sample preparation and subsequent determination of carbazole, trinitrocarbazole (TrNC) and tetra nitro carbazole (TNC) in water samples. Some effective parameters on extraction, such as volume of Triton X-100, extraction time, extraction temperature, ionic...
