Nano hydroxyapatite (Ca10 (PO4) 6 (OH) 2, HAp) has aroused widespread attention as a
green and environmentally friendly adsorbent due to its outstanding ability in removing …

In the present study, the potential of synthesized chitosan/Ag-substituted hydroxyapatite
nanocomposite beads to remove basic dye, heavy metal and microbes from aqueous …

This paper presents an optimization approach for the removal of lead ions (Pb+ 2) by nano-
hydroxyapatite powder form adsorbents that were produced from bovine bone by …

Nano-material of calcium hydroxyapatite (n-CaHAP), with particle size ranging from 50 to 57
nm which was prepared from phosphogypsum waste (PG), was used for the removal of lead …

Chitosan is a well-known sorbent and effective in the uptake of anionic or reactive dyes, but
it has deficiency in adsorption of basic dyes. In this work, chitosan/Fe-substituted …

The effect of the combined application of nano-hydroxyapatite (NHAP) or nano-carbon black
(NCB) on the phytoextraction of Pb by ryegrass was investigated as an enhanced …

Synthesis of neat nano hydroxyapatite (HAp) was carried out using wet chemical
precipitation methods at low temperature and this resulted rod like HAp nanocrystals with a …

Calcium phosphates (CPs) are excellent sorbents, with hydroxyapatite being the most
commonly used for heavy metal removal from ecological samples. The use of more acidic …

Lead (Pb) is one of the ubiquitous soil contaminants. The strategy to increase Pb
phytoremediation is of highly critical considering the difficulty in phytoextraction of Pb due to …

In this study, low-cost and eco-friendly hydroxyapatite (HA) minerals were extracted from
scales of Tilapia fish (Oreochromis mossambicus). After calcination, fish-scale extracted …
