分银后的滤液用氨水络合、盐酸沉钯的方法使钯从液相进入固相
Q Yue
complexing in aqueous ammonia and precipitating out with hydrochloric acid
Explanation:
The complete sentence would be ...following silver separation, the liquid phase palladium in solution is converted to solid phase by (the technique of) complexing in aqueous ammonia and precipitating out with hydrochloric acid...

Note that liquid ammonia and aqueous ammonia are not the same thing, and that precipitating palladium by treatment with acidified aqueous ammonia is a standard technique for its extraction.

Please see explanation below


Explanation:
氨水 - liquid ammonia
络合 - complexing, complexation
盐酸 - hydrochloric acid
沉钯 - 即沉淀钯, extract palladium by precipitation

However, in English scientific articles, the way of describing such processes won't be a word-to-word translation of the Chinese text. Hence, a suggestion for the whole sentence:

...After silver separation, liquid ammonia is added to the filtrate to give the ammonia complex, palladium was then extracted from the solution phrase by forming solid precipitates with hydrochloric acid...

Example sentence(s):
  • Mercury(ii) bromide also dissociates to ionic complexes in liquid ammonia and forms a homogeneous solution
  • 采用硝酸溶解-盐酸沉银-氯化铵沉钯-氨水中和-水合肼还原或煅烧流程可从含钯、银等贵金属废料中回收钯和银

Example sentence(s):
  • The palladium is precipitated out by treatment with ammonium hydroxide, NH4OH, and HCl as the complex PdCl2(NH3)2.
