In this study, SiO2 nanoparticles (nano-SiO2, 20nm) and SiO2 microparticles (micro-SiO2, 150µm) were chosen as carriers for three different enzymes: α-Amylase, papain and trypsin to investigate the effect of particle size on the properties of adsorbed enzymes. The adsorbed amount on 100mg SiO2 particles for α-Amylase, papain and trypsin under their optimum adsorption conditions were 70.93%, 92.26%...
One novel adsorption materials, Mn-loaded iron ore sinter (Mn-IOS), has been conducted to remove arsenate (As (V)) and arsenite (As (III)). The conversion of As (III) to As (V) caused by manganese ion in adsorption progress would be beneficial to adsorption, and therefore, Mn-IOS had a better removal performance of As (III). Results of orthogonal tests suggested that temperature was an important factor,...
Objective: A novel konjac glucomannan-based adsorbent - sulfated konjac glucomannan gel beads (KGMSB) was prepared to selectively adsorb low-density lipoprotein and very low density lipoprotein cholesterol (LDL+VLDL-C) from blood plasma in vitro. 0.5 g of KGMSB was used to adsorb 1.0 mL of blood plasma at 37degC in a shaker at the speed of 200 rpm for 2 h. The adsorption amounts and adsorption rates...
The photoelectron decay characteristic of AgCl micro-crystal, which adsorbed with the green-sensitive cyanine dye, has been obtained by using the microwave absorption and phase-sensitive measurement technique. It is found that when the sensitive concentration is more than 0.2 ml (5.0 mg/ml)/40 g emulsion, the dye J-aggregate is formed on the surface of silver chloride micro-crystals, the free photoelectron...
