泡沫陶瓷基氢氧化高镍催化剂的制备及模拟污水处理研究

本研究以活性炭为造孔剂制备泡沫陶瓷,通过浸渍法使NiCl2负载于泡沫陶瓷,再与NaClO和NaOH混合溶液反应生成NiOOH催化剂.以一定浓度的亚甲基蓝为污水模拟物,亚甲基蓝褪色时间来衡量NiOOH催化剂的催化性能.以催化剂量、次氯酸钠量、pH、温度为变量,分别通过单因素实验和正交试验探究了它们对催化效果的影响以及确定污水处理的较优组合条件.结果表明,在温度为55℃、pH为8、催化剂量为1.0g、NaClO量为15.0mL时,亚甲基蓝的完全褪色时间为131min.各因素对污水处理效果的影响顺序为温度催化剂量pHNaClO量.污水处理的最佳实用组合条件为温度为35℃、pH为8、催化剂量为1.0g、NaClO量为15.0mL.     

A revision of Bovichtus Cuvier, 1831 (Pisces: Bovichthyidae) from Australasia,with description of a new deepwater species from the New Zealand Subantarctic

The genus Bovichtus includes four species from the Australasian region, viz. B. variegatus Richardson, B. psychrolutes Günther, B. angustifrons Regan, and B. oculus n. sp. B. decipiens Regan and Aurion effulgens Waite are junior synonyms of B. variegatus and B. psychrolutes respectively. B. oculus, described from a specimen taken in 847–902 m on the Campbell Plateau in the New Zealand Subantarctic, is the first known deep water Bovichtus species. It differs from all congeners in having a very large eye (horizontal diameter <9·0 times in SL) and, alone with B. psychrolutes, has a patch of ctenoid scales on the body behind the pectoral fin base.

Membraniporoidea,Microporoidea and Cellarioidea (bryozoa,Cheilostomata) collected by Discovery Investigations

Thirty eight species of anascan Cheilostomata are described from the collections of Discovery Investigations, and other British antarctic expeditions. Ten new species are described, including Stomhypselosaria watersi introduced for Cellaria dubia (Busk) sensu Waters (1904). Two new genera are introduced, and Swanomia nom. nov. is proposed for Mawsonia Livingstone 1928, non Woodward 1907.     

Description of two new species of Guernea (Crustacea,Amphipoda, Dexaminidae) from Japan,with tentative revision of subfamily Prophliantinae

Guernea minor sp. nov. and G. ezoensis sp. nov. are described from Japan. Based on these new species and the literature, a tentative revision of the subfamily Prophliantinae is proposed. The subgenus Prinassus of the genus Guernea is invalidated. The subgenus Haustoriopsis of the genus Guernea is re-elevated to a separate genus from Guernea. Dexaminoculus is transferred from Prophliantinae to Dexamininae.     

The larval development of Petalomera japonica (Henderson) (Decapoda,Dromiidae) reared in the laboratory

The complete larval development of Petalomera japonica (Henderson) is described, based on laboratory rearing. The species has two zoeal stages and a megalopa. Detailed comparisons are made with other dromiid larvae, particularly those of Petalomera wilsoni.
