Kd values of Cu, Cr, As in different soil matrix
2007 - IRG/WP 07-50247
Chromated copper arsenate (CCA), a long history of successful preservative, have raised environmental concerns. Adsorption characteristics of domestic soils for chromium, copper, and arsenic were assessed by measuring distribution coefficient (Kd) values of these metal components. The results revealed that Kd values were higher in chromium, followed by arsenic and copper in soil matrix. Different...

Developing Analytical Methods for Determination of Quaternary Ammonium Compounds (DDAC) using HPLC and HPLC-MS (Application to treating solution and preservatives treated wood)
2013 - IRG/WP 13-20516
Korea preservative treating industry has mainly used alkaline copper quaternary (ACQ) expected over 80% of market share in Korea. ACQ employs dodecyl dimethyl ammonium chloride (DDAC) and benzyl dimethyl dodecyl ammonium chloride (DBAC) for active ingredient along with copper. The strongly increasing domestic applications for wood preservatives require developing accurate and reproducible analytic...
