“…Abdulsahib et al (2015) used chitosan, tannic acid and butyraldehyde as the coagulant for removal of bentonite [87]. The Fourier transform infrared spectroscopy (FTIR) analysis of chitosan-tannic polymer revealed that the absorption intensity of OH and NH 2 (peaks 3200 cm −1 , -3700 cm −1 ) from chitosan−tannin polymer is obviously lower than that of OH and NH 2 groups from chitosan, which is correlated to cross-linking reaction occurring between chitosan and tannin.…”

The release of different organic and inorganic water contaminants like halogenated organics, oxyanions, and nitrosamines in the form of solvents, pesticides and even metals that exceed their concentration in the water bodies has destroyed the water ecosystem to a greater extent. These contaminants originate from different point and non-point sources that are inorganic and organic in nature depending on the anthropogenic or natural activity. Although several methods have been utilised and modified to avert the problem, catalysis is among the promising techniques to address the issue. The catalytic reduction method using palladium has been studied extensively. These catalysts are generated using organic and inorganic supports. The use of organic supports is quite useful as they possess a number of functional groups to hold the palladium through different modes of interaction. Based on literature obtained from the different search engines 92 articles have been selected to report the various approaches for the treatment of contaminated water by catalysis. These articles also highlight the methods and characterisation techniques used to decontaminate the polluted water. Thus, we have summarised and interpreted the recent relevant literature related to palladium on suitable support as a potential catalyst for treatment of contaminated water via reduction method.

Detrimental Effect of Tannin on Growth Performance, Visceras Weight and Blood Biochemistry in Broiler Chickens Reared Under Tropical Area

Restriction of antibiotic growth promoters (AGP) in Indonesia reduces broiler production due to bacterial diseases. Some poultry farmers have attempted to replace AGP with phytogenic compounds, such as tannin as an in-feed additive. Therefore, this study was carried out to investigate the effects of tannin administration on the production performance, viscera weight, and lipoprotein levels of tropically-raised broiler chickens. Cobb Strain broiler chicks aged one day were used in an experiment with a completely random design, three treatments, and four replicate pens, each containing nine birds. Three dietary treatments were assigned to the birds: basal diet (negative control), basal diet+0.03% Zn Bacitracyn (positive control), and basal diet+0.05% tannin for the starter phase of 1-21 days and the grower phase of 22-42 days, respectively. Tannin supplementation significantly increased the feed conversion ratio in all phases relative to the control group. Tannin supplementation in the diet significantly reduced daily feed intake during the grower phase, final body weight, carcass weight, intestine weight, liver weight, and total visceral weight, compared to the control group. Tannin had lower levels of aspartate aminotransferase but higher levels of low-density lipoprotein and alanine aminotransferase. Tannin addition in broiler diets might not improve growth performance and health. Therefore, it is not suggested as a substitute for AGPs in broiler diets.
