Abstract

Microalgal residue is an ideal adsorbent for the removal of pollutants in water. Residue modification is effective in improving its adsorption efficiency, while also achieving further extraction of active substances. In this study, ionic liquid was used to extract astaxanthin from the Haematococcus pluvialis residue, and also reprocessed residue was used as an efficient adsorbent for the removal of acid red 88 dye in water. The combination of ionic liquid and solvent of ethanol + soybean oil(1:1)treatment achieved the highest astaxanthin extraction efficiency. Microscopic properties of the algal residue were clearly improved and the average pore size of the residue decreased dramatically from 43.11 nm to 5.23 nm after modification. The maximum removal efficiency of acid red dye by the residue, increased to 99% from 85% after modification. This study provides a new method for the improved extraction of astaxanthin from the Haematococcus pluvialis residue, and modification of the residue, to be further used as an adsorbent.
