Ultrasound assisted polyacrylamide grafting on nano
Polyacrylamide has been grafted onto nanofibrillated cellulose (NFC-g-PAM) under mild conditions. This was accomplished by developing and optimizing an ultrasound assisted protocol in the presence of potassium persulfate initiator.
Microwave assisted synthesis of polyacrylamide grafted starch (St-g-PAM), using ceric ammonium nitrate (CAN) as free radical initiator 1 gm of starch was dissolved in 40 ml distilled water. Desired amount of acrylamide was dissolved in 10 ml water and was added to the starch solution.

3.1.2. Effect of DAC concentration on grafting copolymerization. Fig. 1(b) exhibits the effects of DAC concentration on the [η] and GE of CAD.In Fig. 1(b), both [η] and GE curves showed a gradual decline trend with the increase of DAC concentration, indicating the reduction of the chain propagation reaction rate. This phenomenon can be attributed to reactivity ratios of AM and DAC.
PDA was synthesized by ultrasound assisted aqueous solution polymerization of AM and DMDAAC. The proposed reaction routes for PDA are shown in Scheme 1.A predetermined mass of AM, DMDAAC and other kinds of reagents such as sodium benzoate, EDTA and urea were added into a 250 mL glass vessel with a seal cover.

Polyacrylamide grafted nanofibrillated cellulose Graft copolymerization Ultrasound Intrinsic viscosity ABSTRACT Polyacrylamide has been grafted onto nanofibrillated cellulose (NFC-g-PAM) under mild conditions. This was accomplished by developing and optimizing an ultrasound assisted protocol in the presence of potassium per-sulfate initiator.
Poly(2-hydroxyethylmethacrylate) chains were grafted onto the backbone of agar using a microwave assisted method involving a combination of microwave irradiation and ceric ammonium nitrate to initiate the grafting reaction. The synthesized graft copolymers were characterized by intrinsic viscosity measurements, Fourier transform infrared spectroscopy, elemental analysis (C, H, N, O and S) and

- What are dye industrial wastewater treatment procedures?
- The dye industrial wastewater treatment procedures are a unique key feature in effective trading of dye industry products. The dye industries produce fibers that are further converted into yarn and lastly transformed into textile materials. These materials are prepared by using steps of wet processing.
- Why is wastewater treatment important for textile dyeing & manufacturing?
- Globally, textile dyeing and manufacturing are one of the largest industrial units releasing huge amount of wastewater (WW) with refractory compounds such as dyes and pigments. Currently, wastewater treatment has been viewed as an industrial opportunity for rejuvenating fresh water resources and it is highly required in water stressed countries.
- What technologies are used to treat dye industry wastewater?
- Various technologies such as advanced oxidation process, membrane filtration technique, microbial technologies, bio-electrochemical degradation, photocatalytic degradation have been reported for treatment of dye industry wastewater [ 3, 21–24 ].
- Can synthetic textile dyes be removed from wastewater?
