1. A silica-gel immobilized xanthurenic acid (4, 8-dihydroxyquinoline-2-carboxylic acid) was synthesized and it potential as an adsorbent for metal ions was studied. The silica-gel immobilized xanthurenic acid had an adsorption capacity of about 50 μmol/g for copper ion. This is more than twice that for silica-gel immobilized 8-quinolinol by the same method. Copper, lead and zinc were adsorbed quantitatively from the solution of over pH 1, 2 and 3, respectively.Cadmium, nickel, cobalt and vanadium were adsorbed over pH 4. Many metal ions were adsorbed under a more acidic condition than the adsorbent, silica-gel immobilized 8-quinolinol, because xanthurenic has a carboxyl group in the structure. It was possible to determine sub μg/L levels of trace metals, such as copper, lead, nickel, cobalt, cadmium and vanadium and so on, after a 100-fold preconcentration using this adsorbent and ICP-AES or GFAAS.2. Rapid and simple analysis method was developed for the determination of trace polyethylene oxide non-ionic surfactants using a chelation and an ion-pair extraction as principle.3. Tristimulus colorimeter was used as instrument for the rapid simple and on-site measurement of trace cyanide, ferrous and phosphorous after collection as colored ion associate on an membrane filter.

1.合成了一种硅胶固定化黄尿酸（4，8-二羟基喹啉-2-羧酸），并研究了其作为金属离子吸附剂的性能。硅胶固定化黄尿酸对铜离子的吸附容量约为50 μmol/g。这是用同样方法制备的硅胶固定8-羟基喹啉的两倍多。铜、铅和锌在pH 1、2和3以上的溶液中被定量吸附，镉、镍、钴和钒在pH 4以上的溶液中被吸附。由于黄嘌呤酸结构中含有羧基，因此在酸性条件下吸附金属离子的能力比硅胶固定化8-羟基喹啉强。该吸附剂富集100倍后，与ICP-AES或GFAAS联用，可测定低于μg/L的铜、铅、镍、钴、镉和钒等痕量金属.以螯合作用和离子对萃取为原理，建立了一种快速、简便的测定痕量聚环氧乙烷非离子表面活性剂的分析方法.采用三刺激值比色计作为仪器，通过滤膜收集有色离子缔合物，快速、简便、现场测定痕量氰化物、亚铁和磷。
