The study shows that Zn(II) can associate with NH4SCN and CTMAB to form insoluble ternary ion-association complex, and the precipitate can float on the surface of the liquid phase. A good linear relationship is observed between the floatation yield (E%) of Zn(II) and the amount of CTMAB. On the ground, CTMAB can be indirectly determined by determining E% of Zn(II). The results were satisfactory.展开更多
2006年的葡萄牙,学校如同多米诺骨牌般一所接一所沦陷,政府官员的桌上叠起的疫情报告显示,随着期末考试的临近,先是几十个学生身上出现红疹,眩晕以及呼吸困难的症状,然后疫情很快蔓延至成百上千的学生。引起这些神秘症状的究竟是过敏,...2006年的葡萄牙,学校如同多米诺骨牌般一所接一所沦陷,政府官员的桌上叠起的疫情报告显示,随着期末考试的临近,先是几十个学生身上出现红疹,眩晕以及呼吸困难的症状,然后疫情很快蔓延至成百上千的学生。引起这些神秘症状的究竟是过敏,化学品泄漏还是病毒?经过深入研究,医务人员找到了'病原体':'奶油草莓'或是葡萄牙语'Morangos com Acucar'。不,不是真的草莓——转播媒介最终指向了这一拥有甜腻名字的葡萄牙大热青少年言情剧。展开更多
