A common issue in studies on liquid-phase chemical processes is that the natural solid nanoimpurities present reagent-grade chemicals are ignored. Little known about these impurities’ nature, sizes, concentrations, and behavior, yet they significantly affect efficiency of antiscalants municipal laboratory solutions. Recent research has focused on: (i) estimating nanoimpurity concentrations in-house deionized water semiconductor-grade isopropanol using “light sheet” optical ultramicroscopy, (ii) visualizing antiscalant sorption impurities. Using a fluorescent-tagged aminobis(methylenephosphonic acid) (ADMP-F), we tracked its affinity to particulate matter KCl Our study showed total concentration nanoparticles with size larger than 20 nm 106 units/mL 105 isopropanol. Extrapolation values ≥1 resulted 1011 108 units/mL. The addition or ADMP-F increased foreign nanoparticle populations. selectively adsorbed by only some impurities, while most molecules remain as true solution. To our knowledge, this first instance fluorescently labeled aminoalkylphosphonates being able differentiate traces purity Therefore, role crystallization centers should be seriously reconsidered, especially their important application scale inhibition.
