Abstract - The kinetics of the oxidation of naphthol green B (NGB3-) by Cr2O7 2- has been studied in aqueous hydrochloric acid medium at an ionic strength, I = 0.50 mol dm-3 (NaCl), H+ =1.0 10-4 mol dm-3 (HCl) and T = 25 1C. The redox reaction…
In an effort to improve methane gas production rate from cattle slurry; ethylene diamine- N, N-diacetic acid chelating ligand was introduced into the digester system. Experimental analysis involving the determination of trace metals, pH and methane…
The adsorption of lead(II) ions from aqueous solution with breadfruit’s bark by unmodified and modified with citric acid was investigated. The results by using adsorbent dosage 20 g/L indicated the adsorption efficiency was up to 99%, and the best…
The possibility of utilizing residual forest biomass to produce valuable chemicals was investigated. An outer layer of a bark of Hinoki (Chamaecyparis obutusa) tree, a Japanese cypress, was used as a sample material. Experiments were carried out in a…
