✦ Synopsis

labeled phosphoric a c i d (33P-H3P0t,).

f r e e 33P-Ii3PO~ i d converted t o lead phosphate in t h e preaence of carrier by metathesis with l e a d oxide. Upon hydrogen reduction of t h e lead phosphate, elemental phosphorus is l i b e r a t e d and reacted with c h l o r i n e t o form phorphorua pentachloride. Subsequent reduction in a s p e c i a l l y constructed phoephorue reductor y i e l d s t h e phosphorus t r i c h l o r i d e which i r c o l l e c t e d and s e a l e d in an ampul.
