Novel biodegradable polymeric flocculant based on polyacrylamide-grafted tamarind kernel polysaccharide

Gum ghatti based novel electrically conductive biomaterials: A study of conductivity and surface morphology

“…The polysaccharide gums have a different molecular structure and properties, but their common advantages such as renewable, biodegradable, nontoxic, biocompatibility, etc. make them useful in extensive applications as a commercial polymer in many areas [14,15]. Among the conducting polymers (CPs), polyaniline (PANI) is a well-known versatile conducting material, which has found particular biological utility due to its easy synthesis, low cost, tunable conductivity, and environmental stability [16,17].…”

A Review on Development and Application of Plant-Based Bioflocculants and Grafted Bioflocculants

“…85,102 Conventional redox, microwave-initiated and microwave-assisted grafting methods have been reported to have successfully synthesised plant-based grafted bio-flocculants. 93,[98][99][100] Figure 6 shows the synthesis of grafted copolymers of carboxymethyl starch (CMS), tamarind kernel polysaccharide (TKP), and sodium alginate (SAG) with acrylamide as monomer by using conventional, microwave-initiated and microwaveassisted method. 100 Figure 6.…”

“…92,93,97,99,100 Grafted bio-flocculants synthesised by microwave initiated and microwave assisted methods were proved to provide a better quality grafted copolymers with higher percentage of grafting in comparison with conventional redox grafting method. 99,100 Some research findings showed that the grafted copolymers synthesised by microwave-assisted method presented superior flocculation characteristics when compared with grafted flocculants synthesised by conventional and microwave initiated methods as well as with commercially available non-ionic flocculant (Rishfloc 226 LV). 99,100 Even though grafted bio-flocculants synthesised with microwave technology present superior flocculating characteristics but its usage is concerned with high production cost.…”

In the earlier studies, most of the grafting processes are carried out using domestic microwave ovens in which the irradiation power is generally controlled by on/off cycles of the magneutron.…”

Synthesis, properties and performance of organic polymers employed in flocculation applications

“…Apart from starch, cellulose, gum and chitosan, previous studies had also focused on the synthesis and flocculation efficiency of various synthetic polymers grafted onto other polysaccharides such as agar (10, 11), [25][26][27][28] 39,40 barley (23), 41 tamarind kernel polysaccharide (24), 42,43 carboxymethyl tamarind (25), 44 In addition to these polysaccharides, Sinha et al conducted a graft polymerization of an amphiphilic protein, casein, to produced polymer 26. 45 Various monomers including AM, DMA, NVP, 2-hydroxyethylmethacrylate, and methyl methacrylate (MMA) were used in these studies for the synthesis of grafted polysaccharide polymers.…”
