Formation of Polyacrylamide and PEGDA Hydrogel Particles in a Microfluidic Flow Focusing Droplet Generator
To prepare monodisperse macroemulsions and hydrogel particles, Sigma-Aldrich 330779 mineral oil with addition of ABIL EM 180 nonionic surfactant (Evonic Industries) was applied. The surfactant made the emulsion more stable and prevented its
Typically, for a cement composite, a hydrogel was first prepared by adding polyacrylamide granules (12 g) into water (400 cm 3) producing 3% hydrogel slurry. After allowing the hydrogel beads to swell for 20 min, CaCl 2 (aq, 12.5 cm 3 , 1 wt%)
- Does zeolite remove fluoride?
- Thus, the means of fluoride removal efficiencies grouped by either contact time or zeolite dosage were significantly ( p < 0.05) different. The use of zeolite to remove fluoride in water was investigated in several studies. For instance, 2 g of Mn-Ti modified zeolite yielded about 77% fluoride removal from water [ 16 ].
- How effective is fluoride ion adsorption on modified zeolite?
- The adsorption process has been classified as one of the most efficient methods for the removal of fluoride from water as it is environmentally friendly, easy to operate, and cost-effective. The present study deals with fluoride ion adsorption on modified zeolite.
- Which zeolite is used for fluoride adsorption?
- Clinoptilolite ( (Ca,Na) 2 Al 2 Si 7 O 18 ·6H 2 O, Sigma-Aldrich, St. Louis, MO, USA) was the zeolite used in this study for fluoride adsorption. In order to increase the porosity, the zeolite was thermally treated at 600 °C for 2 h in a muffle furnace.
- Does zeolite reduce turbidity in drinking water?
- The idea behind optimized turbidity reduction followed by the use of zeolite to remove various adsorbates in drinking water is to enhance efficiency of low-cost method of disinfection especially chlorination that is normally used in developing countries.
