Accumulation Characteristics Of Centella Asiatica L. As A Potential Cd-hyperaccumulator In Soil

Dewasa ini, para penyelidik berminat dengan penggunaan penyerap hiper bagi proses pembersihan tanah, terutamanya, yang terkesan dengan pencemaran logam berat. Kajian ini memberi maklumat mengenai tindak balas pengaplikasian kadmium serla kebolehserapan Centella asiatica L. ke atas kadmium di dalam...

Kajian ini memberi maklumat mengenai tindak balas pengaplikasian kadmium serla kebolehserapan Centella asiatica L. ke atas kadmium di dalam sebuah ujikaji terkawal. Tiga kumpulan ujikaji telah dijalankan iaitu bekas yang berisi tanah yang telah dicampur dengan kadmium sebagai kadmium klorida hemi pentahydrate CdCl2.2.5H20 di dalam 15 bekas (diameter = 20 cm, tinggi = 13 cm, 2 kg tanah kering setiap bekas) yg mana dibahagikan kepada tiga kumpulan dan dicampur 10 mg/kg, 25 mg/kg dan 40 mg/kg kadmium di dalam setiap kumpulan.

In this study, Centella asiatica L. has been proposed as a potential cadmium (Cd) hyperaccumulator. A series of pot experiments were conducted in this study.
