3.1. Synthesis of hydrolyzed polyacrylamide grafted polyvinyl pyrrolidone (Hyd.PVP-g-PAM) by microwave assisted method. First of all, a series of five grades of the graft copolymer (PVP-g-PAM) was synthesized by varying the acrylamide concentration and CAN concentration.
Synthesis and optimization of hydrolyzed gum ghatti as
Synthesis of hydrolyzed polyacrylamide grafted gum ghatti (Hyd. GGI-g-PAM) It involves the two step process. Firstly, the long chains of polyacrylamide (PAM) have been developed into the structure of native gum ghatti by microwave assisted method [ 15 ] i.e., synthesis of graft copolymer (GGI-g-PAM).

Microwave assisted synthesis of polyacrylamide grafted
Microwave assisted synthesis of graft copolymer of polymeric blend of Fenugreek seed mucilage (FSM)-Polyvinyl alcohol (PVA) with acrylamide (AM) was done by free radical polymerization using ammonium per sulfate (APS) as initiator. Varying amount of AM and APS was used to optimize the best grade based on highest percentage grafting efficiency and investigated with intrinsic viscosity

- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
- What is a high purity polyaluminum chloride solution?
- High purity (Al-b/Al-T > 90%, Al-13 approximate to 70%) and high coneentration (Al-T > 2.0 mol (.) L-1) polyaluminum chloride (PAC) solution was obtained through membrane distillation followed conventional PAC (0.2 mol (.) L-1) synthesis by quick base injection.
- Does pH affect the performance of polyaluminum chloride (PAC)?
- The performance of PAC was dependent on pH. The synthesized PΑC was efficient coagulant for water treatment. The present work was aimed to synthesis of polyaluminum chloride (PAC) using calcium oxide as a basification agent and optimization of process parameters on the yield of medium polymer species in PAC.
- Which polymers are used to make high-purity PACL?
- After PACl was prepared, the polymers with a sulfydryl group and modified PAM were added into the conventional liquid PACl, this not only removes iron significantly, but also accelerates the sedimentation of insoluble suspended matter. The properties of high-purity PACl synthesized by bauxite and calcium aluminate are shown in Table 3.
