Research Project

  • PDF
Project/Area Number 18580239
Research Category

Grant-in-Aid for Scientific Research (C)

Allocation TypeSingle-year Grants
Section一般
Research Field Irrigation, drainage and rural engineering/Rural planning
Research InstitutionIbaraki University

Principal Investigator

KARUBE Jutaro  Ibaraki University, 農学部, 教授 (10007768)

Project Period (FY) 2006 – 2008
Keywordsイモゴライト / ハロイサイト / 分散凝集 / 土の撥水性
Research Abstract

イモゴライトの特異な凝集の原因は、アルカリ性でイモゴライトの表面が電気的に中性になるためと考えられた。霞ヶ浦湖水の白濁現象の原因としてハロイサイトの可能性が考えられた。土壌の撥水性は、疎水性有機物や含水比、粘土添加等によって大きく変化することが判った。
