Case Study

Low-temperature Synthesis of YAG Nanopowders by Polyacrylamide Gel Method

Su, X., Zhou, et al. Ceramics International, 2016, 42(15), 17497-17502.

Yttrium aluminum garnet (YAG, Y3Al5O12) nanopowder was prepared using the polyacrylamide gel method, and the preparation temperature was much lower than the traditional method.
Preparation process
· Aluminum nitrate (Al(NO3)3·9H2O) and yttrium nitrate (Y(NO3)3·6H2O) were used as starting materials.
· In a typical process, aluminum nitrate and yttrium nitrate were first dissolved in deionized water to obtain a solution. The concentrations of Al3+ and Y3+ in the solution were set to 0.05 and 0.03mol/L, respectively.
· Then the monomers acrylamide (AM) and N-methylene bisacrylamide (MBAM) were added to the solution. The concentration of acrylamide was adjusted to 1 mol/L, 3 mol/L and 6 mol/L, respectively.
· After the monomers were completely dissolved, ammonium persulfate ((NH4)2S2O8), which was used as initiator, was added to the uniform solution.
· In all experiments, the molar ratio of acrylamide/N,N'-methylene-bis-acrylamide/ammonium persulfate was maintained at 24/2/1.
· Stir the mixed solution continuously until a clarified solution was obtained. The solution was heated to 80 °C to form a white gel with three-dimensional network structure. The gel was then dried in an 80 °C oven for a few days to form a xerogel.
· Finally, the xerogel was calcined in air at a heating rate of 5 °C/min for 2 hours at different temperatures to obtain YAG nano-powder.

Synthesis of Cationic Polyacrylamide Flocculant by Low-pressure UV Initiation

Ma, Jiangya, et al. Chemical Engineering Journal. 2017;312:20-9.

At present, a variety of inorganic flocculants are widely used to purify high turbidity suspensions. However, the application of inorganic flocculant in turbid water treatment is limited by the problems such as large amount of inorganic flocculant, high cost, and chemical residue. At the same time, effective organic polymer flocculants, especially cationic polyacrylamide (CPAM), have been developed and widely used in turbidity separation because of their good solid-water separation performance.
Synthesis of Cationic Polyacrylamide PADC
· PADC was synthesized by aqueous solution polymerization via low-pressure UV initiation.
· Dissolve a predetermined amount of main chain monomer acrylamide, cationic monomer DMDAAC, and hydrophobic monomer CDEA in a quartz wide mouth bottle containing 20mL of deionized water.
· The pH of the solution was adjusted with 0.1 molL1 sodium hydroxide and 0.1 molL1 hydrochloric acid.
· The miscible liquids were thoroughly mixed under vigorous magnetic stirring for 30 min at room temperature.
· Subsequently, 0.017 g photo-initiator Irgacure2959 was completely dissolved in the mixed aqueous solution under continuous stirring and inert nitrogen (N2) atmosphere for 15 min.
· The aqueous solution was exposed to low-pressure ultraviolet light (predominant wavelength of 253.7 nm, and power of 24 W) for 90 min.
· Finally, the solid product was obtained after drying in an oven at 105°C for 24 hours.

Synthesis of a Novel Magnetic Polyacrylamide Coagulant

Zhou, Z., et al. Water Science and Technology. 2017, 75(3), 581-586.

A novel magnetic polyacrylamide (MPAM) coagulant was synthesized, with magnetite (Fe3O4) as the core, oleic acid as the modifier, and acrylamide as the monomer, for the removal of suspended solids in kaolin suspension water.
Synthesis of MPAM coagulant
1. Firstly, 0.5g of oleic acid modified magnetite was dispersed into 50 mL water and mechanically stirred for 20 minutes to form suspension A. Then, the solution A was transferred to a three-neck round-bottomed flask running at 40 W C, bathed in water and stirred internally. After adding sodium bisulfite and potassium persulfate in proper proportion, pour nitrogen into the flask for 30 minutes.
2. Then dissolve 25g of acrylamide in 50mL of water to form solution B, and transfer it to the drip funnel fixed on the flask in step 1. Solution B was added dropwise within one hour and the mixture was stirred continuously at 40 °C for 6 hours.
3. Finally, the MPAM was separated and washed several times with acetone, then dried in vacuum for 24 hours.
