Leaching of Arsenic from high Arsenic loaded iron oxide impregnated brick sands (IOI CBCM) was investigated using common household chemicals like common salt and soda ash, the industrial chemicals caustic soda and the phosphates used as fertilizers such as potassium hydrogen phosphate and TSP. Leaching by ordinary ground water was also investigated on the arsenic saturated iron oxide impregnate...

The presence of defects in cold mercerizing of cotton goods led to the creation of a new method, called hot mercerizing in which caustic soda solution is used at a high temperature. Hot mercerizing is successfully used in cotton blended with some other fibers. In cotton/polyester blend fabrics, this treatment serves a dual purpose: subjectively, it imparts a silklike &#10&#10&#10soft handle to ...
