A Study on Developing the Draft of International Standard for the Determination of Perchlorate in Soil Using Ion Chromatography

Autor: Ji-young Kang, Cheon-il Choi, Goon-taek Lee, Min-ki Park, Moon-ju Jeong, Ji-young Ryu, Ji-yang Kim

Publikováno v: Journal of Soil and Groundwater Environment. 20:55-61

Based on the literature study for the determination of perchlorate in soil we chose the ion chromatography as ameasurement method and decided to use 70 mM KOH as an eluent to avoid the interference derived from the co-elutionof pyrophosphate (P 2 O 7

Effect of Differences between Korean Ministry of Environment Standard and ISO Standard on Determination of Petroleum Hydrocarbon Content in Soil

Autor: Ji-In Kim, Wonseok Lee, Goon-Taek Lee, In-Ho Jung, BoKyong Kim, Yong-Hoon Kim, Bo-Hyun Kim

Publikováno v: Journal of Soil and Groundwater Environment. 17:63-72

The main objective of this study is to assess the compatibility between Korean ministry of environment (KME) standard and ISO (KS I ISO) standard for the determination of BTEX and TPH content in soil. We carried out comparison analysis for both metho

Assessment on the Extraction Efficiency of Explosive Compounds in Soil for Improving the Working Draft of International Standard

Autor: Bo-Hyun Kim, Goon-Taek Lee, In-Ho Jung, Dong-Wook Kim

Publikováno v: Journal of Soil and Groundwater Environment. 17:42-46

The ISO document of ISO/TC/190/SC3/WG11/N11 is a working draft of international standard (WD) dealing with analytical method for the determination of explosives and related compounds using high performance liquid chromatography. The scope of this WD

Salinity effects on chlorpyrifos degradation and phosphorus fractionation in reclaimed coastal tideland soils

Autor: Hee-Myong Ro, Eui-Yong Yun, Woo-Jung Choi, Goon-Taek Lee

Publikováno v: Geosciences Journal. 14:371-378

We examined the effect of soil salinity on the degradation of chlorpyrifos and the residual effect of chlorpyrifos and its metabolites on soil P fractionation during 60-day aerobic incubation. A sandy loam soil (Typic Psammaquents) was collected from
