Use of Sponge as an Adsorbent of Cd, Cu, Ni, Co Ions in Water.

Elemental composition of freshwater sponges Drulia uruguayensis and Drulia cristata collected in the Tapajós River

“…Copper, which accounts for 0.08% of the mass of both species of the genus Drulia studied, is reported in the waters of the Tapajos River, less than 1.67 mg/l (1.67 ppm), indicating the ability to accumulate this element by sponges. The absorption capacity of metals, including copper, has been shown to species of marine sponges of the genus Halichondria and Halichlona . Because the two species had the same concentration, we can infer that the mechanism involved is common to the genus and could be exploited for bioremediation and bioidentification of the genus.…”

Atomic Spectrometry Update. Advances in atomic emission, absorption, and fluorescence spectrometry, and related techniques

“…Three strains of sponges have been tested 119 for their ability to adsorb metals (Cd, Co, Cu and Ni). Polystyrene microspheres modified with dithiocarbamate selectively removed mercury 120 from solutions also containing cadmium, copper and lead, and octadecyl silica disks modified with tri-noctylphosphine oxide separated uranium 121 from thorium and other elements in soil samples.…”
