Cr(VI) Ions Removal from Aqueous Solutions Using Natural Adsorbents – FTIR Studies
FTIR Chromium (VI) Rice Straw Hyacinth Roots Saw Dust
2013/3/12
The ability of eight natural adsorbents were investigated for adsorptive removal of Cr(VI) from aqueous solutions. Various physico-chemical parameters such as pH, initial metal ion concentration, adso...
Synthesis of Novel Chelating Adsorbents for Boron Uptake from Aqueous Solutions
boron adsorbent chelating resin uptake capacity
2009/11/13
Two kinds of novel chelating adsorbents have been synthesized to separate boron from aqueous solutions. One is the boron-specific chelating resin, synthesized by the functionalization of macroporous p...
Biosorption of Chromium, Copper, Nickel and Zinc Ions onto Fungal Pellets of Aspergillus niger 405 from Aqueous Solutions
fungus Aspergillus niger 405 heavy metals biosorption
2009/3/23
Fungal mycelium pellets of Aspergillus niger 405 were used for adsorption of different metal ions. The biosorption of Cu2+, Zn2+, Ni2+ and CrO42- was studied over a range of metal ion concentrations, ...
Effect of ethanol on interactions of bitter and sweet tastes in aqueous solutions
sweetness bitterness ethanol sucrose Aspartame Neotame sensory analysis
2014/3/3
Experimental samples simulated the composition of vermouths. In all experiments, 0.01% quinine was used as a standard bitter substance. Sucrose increased the acceptability in the concentration range o...

2014/3/17
Sensory profiles of saccharin, acesulfame K, aspartame, and neotame were compared with that of sucrose in three different types of water (tap water, commerical Crystalis water, and distilled water) un...
Thermal Analyses of Polyol-Aqueous Solutions at Temperatures below 0°C
polyol sorbitol freezing point thermal analysis
2010/11/22
The thermal properties of polyol-aqueous solutions (xylitol, sorbitol, maltitol and lactitol) in concentrations from 5% to 30% (0.15-2.86 molal) were analyzed by differential scanning calorimetry at t...
Freezing Point Depression of Polyol-Aqueous Solutions in the High Concentration Range
freezing point depression polyol xylitol
2010/11/22
Freezing points of polyol-aqueous solutions (xylitol, sorbitol, maltitol, lactitol, and hydrogenated corn syrup) were measured in the high concentration (30-60%) range and compared with those of their...
