It is measured … The ionic CPBs include anionic and … Krafft Point This is the temperature below which the surfactant is, basically, a useless solid. To be more scientific, it is the temperature at which the solubility is equal to the CMC, so below that temperature you cannot obtain micelles so much of the interesting stuff that occurs with surfactants cannot happen. They are mostly of no interest because surfactants are usually used in the context of oil/water mixes and then the interest is in the change of HLD with temperature (driven by the same effect of lower hydrophility), and so the HLD equation is more relevant than cloud point. A cloud-point reproducible to ±0.2C can be determined from the cloud-o-gram. Salts depressed the cloud point of nonionic surfactants at all hydrochloric acid concentrations examined. Advanced. The effectiveness of two different surfac- This technique is mainly based on the use of surfactants as extractants, involving the transference of a surfactant from one liquid to another after heating. The test tube contained 5 mL . Cloud Point Surfactants However, too high temperature might lead to analyte losses. Alcohols, methanol and isopropanol enhanced the cloud point of nonionic surfactants. Based on this, the salting-out effect was introduced as an alternative to induce the phase separation. A number of compounds can raise the cloud point of nonionic surfactants. BEROL 185. DeIONIC 100-VLF: A virtually non-foaming wetting agent with properties similar to DeIONIC LF-60. Cloud point. Water of hydration improves the solubility of these materials. What is Cloud-point Extraction (CPE)?
