Background and Aim: Irradiated chitosan can be used as a matrix for slow-release urea (SRU) production. This study aimed to (1) determine the optimal formulation of irradiated controlling nitrogen release (2) evaluate characteristics SRU in vitro fermentation based on feed supplement. Materials Methods: In first phase investigation, four chitosan-based formulations with varying amounts acrylamide (3 5 g) gamma irradiation (5 10 kGy) were evaluated. Scanning electron microscopy, Fourier...

Abstract As chitosan and glycerol are mixed, they form a polymer blend that can be processed into edible films, or other plastic-like materials. Chitosan-glycerol mixing generates properties of edible, which means it break down non-toxic components over time through natural processes, reducing its environmental impact. In this work, film is contained chitosan-glycerol films were prepared by evaporation casting from solution. Edible placed on the polyethylene packages irradiated Co-60 gamma...

Radiation-induced graft polymerization using gamma rays was used in our previous study to synthesize a bacterial cellulose co-polyacrylamide adsorbent (BC-PAAM). In this work, the adsorption capacity of BC-PAAM towards copper and lead metal ions investigated batch system under various parameters such as contact time initial concentration ion. The pH solution kept at 5 during process. equilibrium data is also interpreted from Langmuir Freundlich isotherms find most appropriate isotherm...

Abstract The bacterial cellulose‐ co ‐polyacrylamide (BC‐PAAM) is successfully synthesized by radiation‐induced graft polymerization using gamma rays with the simultaneous technique. optimum irradiation dose applied 50 kGy and mass ratio among acrylamide (AAm) cellulose (BC) 1:4. sorption of aqueous Cu Pb onto BC‐PAAM investigated in relation pH 3 5. heavy metal ions are as single during adsorption study. uptake shows that capacity higher at 5 compared to 3, both for ions. obtained condition...

Abstract Zeolite‐g‐polyacrylamide is prepared by using the radiation induced grafting technique. Clinoptilotite, a natural zeolite, used as base matrix. In order to increase degree of grating polyacrylamide into its surface modified with silane compound before reaction and applied poor solvent method in reaction, i.e., mixture toluene H 2 O. The irradiation doses are varied from 10 50 kGy. parameters 40% w/w acrylamide, temperature 60 °C 3 h time. highest 93% at an dose 25...

The Wallacean region of Indonesia, specifically the Nusa Tenggara and South Sulawesi regions in carry a large population cattle. Therefore, it is necessary to evaluate methane production from forage-based feed this region. objective study was determine effect supplement containing Andrographis paniculata irradiated chitosan on vitro fermentation production, rations This evaluates five forages that are mainly used as ingredients by smallholder farmers nnamely, (Sorghum forage, Pennisetum...

Black liquor is one of by-products in the synthesis bioethanol from Palm Oil Empty Fruit Bunch (POEFB). The black contains lignin-cellulose that has natural antioxidant activity even without help gamma irradiation which, generally, proportional to number radicals within lignin. objective this study examine effect dose on lignin irradiated under air atmosphere condition and at variations 0 75 kGy. measurement radicals, qualitatively quantitatively was measured using an electron paramagnetic...

Abstract This study investigated the application of amidoximated bacterial cellulose (AMO-BC) film for lead (Pb) adsorption from aqueous solutions. In our previous study, has been successfully modified through amidoximation to enhance its metal capacity. order modify (BC) film, acrylonitrile was grafted onto it initiated by an electron beam create BC-grafted-polyacrylonitrile (BC-g-PAN). After that, generated when BC-g-PAN reacted with hydroxylamine hydrochloride add amidoxime functional...
