Abstract
Organic and inorganic pollutants it poses a great danger to the environment and public health it is considered one the water pollutants due to the toxicity results, even at low levels. Although there are several methods or techniques for treating or removing dyes form an aqueous solution or purification of water from Chlorella Vulgaris algae,however;it is often not economical. In this letter contains an introduction that gives a brief idea about water pollution by different pollutants such as dyes ,acid violet17, acid red 151, acid black194,malachite green,crystal violet,methlen blue also different ways to removal dyes from the aqueous solution.There are some previous studies in this letter which shows the removal of dyes using low-cost materials such as clays and know the types of clays.
In this letter various dye solutions were prepared,as well as an aqueous solution contaminated with unicellular algae and use of different measuring devices such as pH meter and UV through which different percentages of dye removal are estimated and purification water from unicellular algae by using two types of clay available in the Egyptian environment are bentonite and kaolin Also activate them using the acidic activated (Hcl), basic activated (NaoH) and comparison between them.In this letter some analyzes were done on the clays such as FTIR,X-RAY,SEM and application of the ability of clays with Freundlich, Langmuir, Temkin isotherm models and determine the correlation coefficient for dyes ,comparison between them.
