BACKGROUND Curcumin and vanillin are the two useful compounds in food and medicine. Bismuth nitrate pentahydrate is an economical and ecofriendly reagent. METHOD Bismuth nitrate pentahydrate impregnated montmorillonite KSF clay and curcumin were subjected to microwave irradiation. RESULTS Microwave-induced bismuth nitrate-promoted synthesis of vanillin from curcumin has been accomplished in...
Palygorskite clay has been investigated as low cost and ecofriendly adsorbent for the removal Basic Red 2(BR-2) from aqueous solution. Batch adsorption studies are carried out by observing effect of amount of adsorbent dose, contact time, pH, initial concentration of ( BR-2) and particle size of adsorbent on the adsorption capacity of the adsorbent were studied. Adsorption data fits the Langmui...
Plastics are low molecular weight organic materials, that are non degradable in the natural environment. Generation of plastic waste constitutes a major part of Municipal Solid Waste. This creates a lot of environment pollution, which in turn affects ecosystem and human health. The solution to tackle this dreadful situation lies in following 3R namely Reduce, Reuse and Recycle. Waste plastics c...
Colloidal gold is very attractive for several applications in biotechnology because of its unique physical and chemical properties. Many different synthesis methods have been developed to generate gold nanoparticles (AuNPs). Here, we will introduce these methods and discuss the differences between fabrication techniques. We will also discuss ecofriendly synthesis methods being developed to effi...
Recently, different methods have been proposed to develop wood materials, termed “densified woods”, with density increment and improvement in mechanical proprieties. Almost all the involve use of reducing agents strong bases. In this work, a new method has developed involving less polluting agents. The formation densified woods is divided into two steps: delignification involves removal lignin,...
