Zeolite '93: 4th International Conference on the Occurrence, Properties, and Utilization of Natural Zeolites

1993年6月20日至28日，第四届天然沸石的发生、性质和利用国际会议将在爱达荷州博伊西举行。会议将由国际天然沸石委员会和纽约州立大学布罗克波特学院主办。预计将有来自30多个国家的200至250名与会者。Zeolite '93将汇集地质学家、矿物学家、表面化学家、晶体学家、采矿工程师、卫生工程师、农业工程师、石油工程师、化学工程师、农学家、园艺学家、动物科学家、水产养殖业家和营销专家，共同讨论天然沸石领域的最新科学发现和活动。会议将包括四天的技术会议，一周中，所有参与者对爱达荷州西南部的一个主要沸石矿床进行实地考察，以及三天的会议后可选的对俄勒冈州东部重要沸石矿床的实地考察。邀请的专题讨论会将于每天上午举行，讨论沸石研究的最重要领域，然后在下午对所有提交的论文进行海报展示，不受其他技术活动的反对。Zeolite '93将讨论天然沸石的所有科学和技术方面——它们在火山沉积地层中的成岩作用，它们在油藏孔隙空间中的分布，它们的基本晶体结构和矿物学特征，以及它们的结构控制的离子交换、吸附、水合脱水和催化性质。将讨论这些材料最近开发的许多应用背后的基础科学，包括它们作为植物生长中氮的缓释载体；作为动物营养的膳食补充剂；作为饮用水和市政、工业和农业废水中铵的过滤器；作为核废水和泄漏中的放射性铯和锶的脱矿剂；作为遏制核废料的障碍；作为交换剂，从饮用水、工业废水、采矿和铣削废料中去除铅、镉和铜；作为宠物粪便和饲养场粪便的氨吸附剂；作为冰箱和医疗设施的除臭剂；作为无土农业的基质，也就是所谓的植耕法。

Zeolite '93, the 4th International Conference on the Occurrence, Properties, and Utilization of Natural Zeolites will be held in Boise, Idaho, June 20-28, 1993. The Conference will be sponsored by the International Committee on Natural Zeolites and the State University of New York, College at Brockport. Between 200 and 250 participants are expected from more than 30 countries. Zeolite '93 will bring together geologists, mineralogists, surface chemists, crystallographers, mining engineers, sanitary engineers, agricultural engineers, petroleum engineers, chemical engineers, agronomists, horticulturalists, animal scientists, aquaculturalists, and marketing specialists to discuss the latest scientific findings and activities in the growing field of natural zeolites. The Conference will comprise four days of technical sessions, a mid-week, all-participant field excursion to a major zeolite deposit in southwestern Idaho, and a three-day, post- conference optional field trip to important zeolite deposits in eastern Oregon. Invited symposia will be held each morning on the most significant areas of zeolite research, followed by afternoon poster presentations of all submitted papers, unopposed by other technical activities. Zeolite '93 will treat all scientific and technological aspect of natural zeolites--their diagenesis in volcanogenic sedimentary formations, their occurrence in pore spaces in petroleum reservoirs, their basic crystal structure and mineralogical character, and their structure-controlled ion-exchange, adsorption, hydration-dehydration, and catalytic properties. The basic science behind many of the recently developed applications for these materials will be discussed, including their use as slow-release carriers of nitrogen for plant growth; as dietary supplements in animal nutrition; as filters of ammonium from potable water and municipal, industrial, and agricultural wastewaters; as demineralizes for radioactive cesium and strontium in nuclear effluents and spills; as barriers in nuclear-waste containment; as exchangers to remove lead, cadmium, and copper from drinking water, industrial effluents, and mining and milling wastes; as ammonia sorbents for pet litters and feedlot manures; as deodorizers in refrigerators and medical facilities; and as substrate in soilless agriculture, so-called zeoponics.
