Adanson, who derived the genus name from the Chinese epithet for one of the species, described the genus Kalanchoe in 1763. The species name luciae honours Lucy Dufour, for whom this species was named by Raymond Hamet in 1908.. The genus Kalanchoe occurs most abundantly in Madagascar but also throughout Africa, Cyprus, Indochina and is a very well .

10/04/2018 · Removal of emerging pollutants, such as pharmaceuticals, from wastewater is a challenge. Adsorption is a simple and efficient process that can be applied. Clays, which are natural and lowcost materials, have been investigated as adsorbent. In this work, raw vermiculite and its three modified forms (expanded, base, and acid/base treated) were tested for removal of a widely used .
