Evaluation of Copper-Chromium-Arsenic Preservatives Fixation on Wood by Measuring the Density of Surface Electric Charge

표면전하밀도(表面電荷密度)를 이용(利用)한 동(銅)·크롬·비소계(砒素系) 방부방충제의 정착(定着)에 관(關)한 연구(硏究)

This study was attempted to propose a method evaluating fixation of active ingredients in Copper-Chromium-Arsenic preservatives treatment. Fixated amount of active ingredients on wood was obtained by measuring the density of surface electric charge based on $\varsigma$ potential. Data accumulated from density of surface electric charge showed that the fixated amount of preservatives on wood increased linearly as concentration of treating solution increaced, which indicatied quantitative reactions in fixation of preservatives.
