ISO 9073-12:2002, Textiles - Test methods for nonwovens - Part 12: Demand absorbency
ISO 9073-12 describes a method for the evaluation of the absorbency of fabrics when one side is in contact with a liquid and the fabric is under mechanical pressure.This test is designed to allow comparison of absorbent materials such as nonwovens and is not intended to simulate in-use conditions of finished products.Demand absorbency is also called demand wettability..

Decolorization of a baker's yeast industry effluent by Fenton oxidation [An article from: Journal of Hazardous Materials]
This digital document is a journal article from Journal of Hazardous Materials, published by Elsevier in . The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: Baker's yeast industry is an important industry in Turkey. Molasses is used as a raw material, which is an end product of sugar industry. Baker's yeast industry effluents contain various pollutants and are generally characterized with high chemical oxygen demand (COD), TKN, dark color and non-biodegradable organic pollutants. The objective of this study was to investigate the decolorization and the removal of non-biodegradable organic pollutants measured as mainly DOC, SUVA"2"5"4, SUVA"2"8"0 and COD parameters. Fenton oxidation was applied to biologically pre-treated effluent of full-scale wastewater treatment plant. Jar test method was used to determine the best operating conditions. The 600mg/L H"2O"2/600mg/L Fe^2^+ dosage was quite enough to obtain a high color removal efficiency of 97%. However, the best Fe^2^+/H"2O"2 dosage was 1200mg/L Fe^2^+/800mg/L H"2O"2 at pH 4 and in reaction time of 20min for mineralization of DOC and COD. For these conditions, the maximum color removal efficiency was obtained as 99%, maximum DOC and COD removal efficiencies were obtained as 90 and 88%, respectively. Also, SUVA"2"5"4 and SUVA"2"8"0 values decreased. .

Utilization of starch and clay for the preparation of superabsorbent composite [An article from: Bioresource Technology]
This digital document is a journal article from Bioresource Technology, published by Elsevier in 2007. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: Starch and attapulgite were utilized as raw material for synthesizing starch-graft-poly(acrylic acid)/attapulgite superabsorbent composite by graft copolymerization reaction of starch and acrylic acid (AA) in the presence of attapulgite micropowder in aqueous solution. Major factors affecting on water absorbency such as weight ratio of AA to starch, initial monomer concentration, neutralization degree of AA, amount of crosslinker, initiator and attapulgite were investigated. The superabsorbent composite synthesized under optimal synthesis conditions with an attapulgite content of 10 wt% exhibit absorption of 1077 g H"2O/g sample and 61 g H"2O/g sample in distilled water and in 0.9 wt% NaCl solution, respectively. This superabsorbent composite with excellent water absorbency and water retention under load, being biodegradable in nature, economical and environment-friendly, could be especially useful in agricultural and horticultural applications. .
