agricultural research nata de coco - The preparation was carried out through three stages, including: the breakdown of Nata de coco, activation with sulfuric acid, and modified with ethylenediamine. Born-fi film showed a different behavior of two different membrane preparation before with regard to mechanical properties and structure. Established film grains have a strong mechanical properties, are usually brittle Nata is activated, while the Born-IT is very strong. The infrared spectrum of the three types of membranes (pure Born, Born activated, and the Born-en) usually does not change significantly, but the UV-VIS spectra of the variation of the peak wavelength of each film.
agricultural research: nata de coco
Nata own membrane has a maximum wavelength at 270 nm, 270 nm Nata activated, while a membrane-Nata at 295 and 300 nm, respectively Nata-one, prepared by the activation of a long 15 minutes and 45 minutes . Nata a membrane-damaged structures, either in water or ethanol with the time required for decomposition, respectively, and 3x15 minutes 2x15 minutes. Each parameter has an influence on the ability to study the membrane-en Nata ions to bind Cu (II). Membrane-Nata a demonstrated ability to bind Cu (II) with optimum at the time of preparation using 2 M sulfuric acid for 30 minutes and the concentration of 1.8 M. ethylenediamine.
