Metal adsorption acrylic fiber, non-woven fabric, sheet-like product, and uses thereof as metal adsorbent

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 (C.sub.1) (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 (C.sub.2) (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 (%)={(C.sub.2−C.sub.1)/C.sub.2}×100.

Water stable copper paddlewheel metal organic framework (MOF) compositions and processes using the MOFs

This invention relates to a Cu-BTC MOF which is water stable. The Cu-BTC MOF has been modified by substituting some of the BTC ligand (1,3,5, benzene tricarboxylic acid) with 5-aminoisophthalic acid (AIA). The resultant MOF retains at least 40% of its as synthesized surface area after exposure to liquid water at 60° C. for 6 hours. This is an unexpected result versus the MOF containing only the BTC ligand. This MOF can be used to abate contaminants such as ammonia in gas streams and especially air streams.
