Title:

METAL ADSORPTION ACRYLIC FIBER, NON-WOVEN FABRIC, SHEET-LIKE PRODUCT, AND USES THEREOF AS METAL ADSORBENT

Document Type and Number:

WIPO Patent Application WO/2013/111857

Kind Code:

A1

Abstract:

A metal adsorption acrylic fiber wherein the strontium adsorption rate is 85% or more when the strontium adsorption rate is measured using the following measurement method. A strontium adsorption rate measurement method (strontium 0.1 ppm measurement method) involves immersing a metal adsorption acrylic fiber into an immersion fluid, collecting the immersion fluid as a testing solution 24 hours after beginning the immersion, analyzing the quantity of strontium in the testing solution, obtaining the concentration (C1) (ppm) of strontium in the testing solution, creating a contrast solution, analyzing the quantity of strontium in the contrast solution as in the case with the testing solution, obtaining the concentration (C2) (ppm) of strontium in the contrast solution, and calculating the strontium adsorption rate of the metal adsorption acrylic fiber by using the following equation: strontium adsorption rate (%) = {(C2-C1)/C2}×100.
