Carbamazepine CBZ is a ubiquitous micropollutant in wastewater and reclaimed water In this study we evaluated CBZ degradation by light emitting diode LED driven UV/chlorine oxidation
The water absorption capacity WAC of starch is an important functional property that reflects the degree of starch water interactions The water absorption process of the starch is shown in Fig starch is added to water the water molecules pass through the surface of the starch granules into the interior; As water molecules continue to penetrate they eventually
In soil mechanics pore water in soil is commonly classified into bound water and free water The structure and properties of bound water differ significantly from bulk water due to the strong attraction by the surface of soil particles Osipov 2012 Although bound water contains a few layers and occupies a small percentage of pore water in saturated soil it has a great
DOI / Loess is a wind blown deposit generally low in clay content Despite being strongly hydrophilic there is a lack of detailed investigation of bound water on loess particle surfaces An integrated approach incorporating isothermal adsorption and thermogravimetric analyses was applied to determine the content of different
The correct positions of the deuterium D atoms of many of the bound waters in the protein concanavalin A are revealed by neutron Laue diffraction including cases where these water D atoms show enough mobility to render them invisible even to ultra high resolution synchrotron radiation X ray crystallography The correct positions of the deuterium D atoms
The determination of average water saturation in preserved samples requires extracting water from the samples using hot toluene vapors followed by collection of the extracted water
literature for the determination of moisture water determination each category of food and non food products presents certain distinctive features although not essential regarding the work procedure According to the nature of the evaluated compound these methods have been described directly water

This makes the determination of water mobility in the matrix problematical The water molecules in bound and unbound environments would be expected to exhibit different mobilities although exchange between the different environments can be very rapid so individual molecules are unlikely to exist in a specific state for long
Abstract Loess is a wind blown deposit generally low in clay content Despite being strongly hydrophilic there is a lack of detailed investigation of bound water on loess particle surfaces An integrated approach incorporating isothermal adsorption and thermogravimetric analyses was applied to determine the content of different types of bound water on the
Abstract The article presents the results of a comparative study of two drying methods over a dehydrating medium and differential scanning calorimetry Measurements of the amount of free and bound water were performed in plant tissues with different osmotic pressures of the cytoplasm The results of the comparison revealed a number of limitations for both
SUMMARY— A Nuclear Magnetic Resonance NMR instrument was used to measure the amount of liquid water in a complex colloidal system over a broad temperature range The bound water content defined as that which remained liquid at 0°F −18°C was ± g water per g dry solid in case of a wheat flour dough This value was independent of total moisture content
Relaxation times were measured to obtain information on strongly bound water bound or hydration water and weakly bound water in food Damez and Clerjon 2013 Pearce et al 2011 Determination of water content After NMR T 2 relaxation measurements water content of samples was determined by oven drying 5 g of sausage samples at 105 °C

The bound water in fine coal filter cake represents the water that cannot be removed using mechanical dewatering techniques The amount of bound water in a fine coal filter cake in other words
Adsorption and combustion of organic bound fluorine Determination of the AOF in river water samples was divided in three steps following a modified protocol of ISO 9562 2004 09 i adsorption of the organic fluorine on AC columns ii combustion of the AC and absorption of released hydrogen fluoride in a trapping solution and iii
Earlywood EW and latewood LW have different hygromechanical behaviors if subjected to relative humidity RH variations To understand this effect better the adsorption mechanisms of EW and LW of Douglas fir were studied by 2D 1 H NMR relaxometry under conditions of equilibrium moisture content EMC at 20°C Two bound water components were detected with
