Recent reports on biosorbents based on diverse types of macrophytes are found widely in the literature. Free-floating aquatic plants from the genera Salvinia, Azolla, Eichhornia, Lemna, and Pistia have been described the most. S. natans biomass was able to uptake As(V) at low initial concentrations from 0.25 to 2 mg/L (74.8% and 54%, respectively). The experimental data fitted well to both Langmuir and Freundlich isotherms. The effect of pH and biomass quantities on sorption rate has also been investigated along with some metabolic parameters.105...

The water hyacinth Eichhornia crassipes originates from Brazil, and although it represents one of the most troublesome and invasive of water weeds, it is also one of the best phytoremediants of polluted water. The biomass becomes saturated with pollutants, which can then be removed from the water by harvest of the biomass and its composting, a process which achieves a substantial reduction in the mass requiring further processing (e.g., incineration under controlled conditions). The species is highly susceptible to frost, but in frost-free environments, its introduction is risky as it can readily become uncontrollable.

The occurrence of the diester structures of the malonic acid moiety in natural anthocyanin pigments has so far been reported in pigments from flowers of Eichhornia crassipes and chive. Allium schoenoprasum, where the anthocyanin-flavone and anthocyanin-flavonol disubstituted malonate structures were exhibited, respectively (Figure 10.8 and Figure 10.9). In some anthocyanins from flowers of Anemone coronaria, malonic acid is esterified with galactose in one end and tartaryl in the other end. ... 

A family of tropical and warm areas, particularly of North America, the Pontederiaccae has a few north temperate species. Possibly the most familiar is the aquatic weed Eichhornia.

To determine the effects of the deprivation of specific micronutrients on the water hyacinth (Eichhornia crassipes), Colley et al. (1979) studied the rate of uptake of iron and manganese in comparison with phosphorus. Results indicated that all three elements were actively absorbed by the root systems, but the rates of absorption differed markedly. The rate of absorption of manganese by roots was 13 and 21 times that for radio-iron and -phosphorus, and iron was taken up by the roots at nearly twice the rate of phosphorus. Manganese translocation appeared to be faster than phosphorus translocation by an order of magnitude and 65 times faster than iron translocation. 

EPS was used to show that Pt on precipitates on the surfaces of roots of Eichhornia crassipes grown in nutrient with added (NH4)2[PtCl6] was Pt(IV) and had not been reduced by the roots (Parsons and Farago, 1987). The technique was used to study Al on the surfaces or barley roots, in Al-sensitive and tolerant plants grown in the presence of Al. Al-tolerant roots contained 21 °7o Al as the phosphate, whereas the sensitive roots contained only 1.3% Al (Millard et al., 1990). The method which is useful...
