Phytoremediation Ability of Ornamental Plants Celosia argantea L. and Mirabilis jalappa L. in Plumbum (Pb) Contaminated Soil

Plumbum or lead is a type of heavy metal that dangerous if it has exceeded the threshold 0.07 µg/g based on National Standardization Agency SNI 2004. This found in nature such as soil, water, and air. The purpose study was to determine phytoremediation ability two types ornamental plants, namely Celosia argentea L. Mirabilis jalappa L., against (Pb) soil. growth parameters observed consisted plant height, stem diameter, number leaves, leaf length, width. ICP-MS (Inductively coupled plasma-mass spectrometry) used analyze plumbum content soil plants. results ofinitial analysis prior planting process (phytoremediation) were 103.17 which had predetermined threshold. result after showed 49.685 1,9548 Similarly, Ph 47.802 5.3077 Based biomass calculation obtained 18.84% 27.85%, respectively. percentage Pb removal 51.842%, while 53.667%. efficiency absorption 1.895% 5.145%, In conclusion, Ornamental plants are able act agents for pollutes evidenced by decrease levels process.Keywords: (Pb), Phytoremediation,
