气相色谱法测定废水中的茚及芳烃混合物

本文采用气相色谱法，选择中等极性的Ｔｒｉｃｒｅｓｙｌｐｈｏｓｐｈａｔｅ与高沸点的非极性ＡｐｉｅｚｏｎＬ配成混合固定液，测定工业废水中的茚及芳烃混合物。该方法灵敏度高，再现性好，简便快速，适合测定化工、制漆、制茚树脂生产所排放的废水，同时也能检出受苯系物及高沸点的不饱合物萘等多组分污染的水体

A review of the use of mineral wastes and by-products in road construction

The use of mineral and mineral-related wastes in road construction in Britain is reviewed. Only iron and steel slags have potential for use in road pavement layers and most wastes require modification before being suitable for sub-base construction. The principal outlet for wastes is as substitutes for bulk fill and the advantages and disadvantages of this use are considered. A dual-tendering system to assist decision making is described and results presented for its recent use in Britain.Crown Copyright 1979.
