TL;DR: In this paper, a combination of ammonium pyrrolidine dithiocarbamate/methyl isobutyl ketone (APDC-MIBK) microextraction and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was used for Cd concentration determination in aqueous samples.
Abstract: Herein, we proposed a high matrix tolerance analytical method, using a combination of ammonium pyrrolidine dithiocarbamate/methyl isobutyl ketone (APDC-MIBK) microextraction and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), for Cd concentration determination in aqueous samples. Only 200 μL of organic solvent was used throughout the entire analysis process, with enhancement factors as high as 25. Recoveries from replicate analyses of natural water [ NIST 1 640(a)] c ontaining m ean c oncentrations o f 3 .1 μ g C d L –1 were 95 ± 3. The corresponding Cd detection limit was 0.6 μg L–1. The main advantage of this approach is its simplicity in terms of sample preparation, as demonstrated by quantifying the Cd levels in tap water, groundwater, and seawater, using a standard addition method.

TL;DR: In this article, a polyurethane resin having an improved sealing effect against fouling matter from the base material, comprising an isocyanate prepolymer obtained by the reaction between a polyether polyol and a polymethylene polyphenyl isOCyanate, and a diluting solvent, is presented.
Abstract: PURPOSE:A polyurethane resin having an improved sealing effect against fouling matter from the base material, comprising an isocyanate prepolymer obtained by the reaction between a polyether polyol and a polymethylene polyphenyl isocyanate, and a diluting solvent CONSTITUTION:A polyether polyol, MW 200-3,000, is used as a polyol component This compound is reacted with a polymethylene polyphenyl isocyanate to yield an isocyanate prepolymer having a free isocyanate group content of 10-25%, based on the weight of resin solids Next, the moisture-curing polyurethane resin of the purpose is obtained by diluting the prepolymer with a diluting solvent to form a resin solution having a concentration of, preferably, about 30-60wt% The diluting solvents which are used include, for example, toluene, ethyl acetate, and methyl isobutyl ketone

TL;DR: The extract agent for metal ion (methyl isobutyl ketone, etc), organic phase containing the water insoluble organic solvent (kerosine, etc) and the water phase containing reducing agent (sulfurous acid, etc).
Abstract: PURPOSE:To produce noble metal particles in water drips in oil by adding water drips in oil type emulsion composing of metal ion extract agent, organic phase containing water insoluble organic solvent and water phase containing reducing agent into noble metal salt water solution CONSTITUTION:The extract agent for metal ion (methyl isobutyl ketone, etc), organic phase containing the water insoluble organic solvent (kerosine, etc) and the water phase containing the reducing agent (sulfurous acid, etc) are mixed under existence of surfactant (sorbitan monooleate, etc) to produce the water drip in oil type emulsion This water drip in oil type emulsion is added into the noble metal salt aq solution to develop the noble metal particles (Au, Pt, Pd, Rh, Ir, etc) in the water drip in the oil By this method, the noble metal is concnd and recovered and the fine particles are produced
