✦ Synopsis

The ku&~cs of absorptmn of phosphme m aqueous solutnms of sodmm hypochlonte and sulphunc acti was studied m a stwred cell and a s-d contactor The reachon of phosphme with aqueous soh~t~ons of sodmm hypockdonte was found to be first order with respect to phosphme and hypochlor& The effect of pH on the second order rate constant was also mvesmted The value of the second order rate constant was found to vary from 230 to 77,000 1 /g mole set at 28oC m the pH range of 12 95-9 40 The reachon of phosphme with aqueous solutions of sulphunc acxl, m the range of concentrations of 80 to 92% by wetit, was also found to be first order with respect to phosphme The value of the pseudo first order rate constant was found to be m the range of 3 x 10664 x 106 set-' at 28°C Copper sulpbate was found to be an effe&ve catalyst m sulphurx acid solutions -INTROMTCTION
