in this study, in order to constitute polyelectrolyte multilayers (pem) using layer-by-layer nanotechnology, recycled fibers were subsequently treated with cationic starch (cs) and anionic starch (as) multi-layers each layer conducted at neutral ph for 10 minutes. also, to compare with mechanical of refining, the pulp was refined for 25 minutes to the freeness of about 291 ml.csf using valley b...
In this study, oil was extracted from the liver and visceral fat of Patin (Pangasianodon hypophthalmus) and refined. The yield of oil after refining was 49.98%. The major yield loss (34.20%) happened during the degumming procedure. Fatty acids found in the crude and refined oil were C12:0, C14:0, C14:1, C16:0, C16:1, C18:0, C18:1, C18:2, C18:3, C18:4, C20:0, C20:1, C20:4, C20:5, and C22:6. The ...
