ʻO nā kristal cubic kala ʻole a keʻokeʻo.ʻAʻala ʻole, me ka ʻono ikaika a paʻakai.Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka ethanol, methanol, acetone, glycerin a me ka amonia wai, hiki ke hoʻoheheʻe ʻia i ka etera.ʻAʻole kūʻokoʻa a alkaline iki paha kāna ʻano wai.
Hoʻohana
(1.) Hoʻohana mau ʻia e like me nā reagents analytical, a hoʻohana pū ʻia i ka hoʻomākaukau ʻana i nā emulsifiers photosensitive kiʻi a ma ka ʻoihana lāʻau lapaʻau.
(2.) Hoʻohana ʻia i ka emulsion photosensitive, soap, lithography, organic synthesis, lāʻau lapaʻau, meaʻai additives, etc.
(3.) ʻO ka potassium iodide he mea hoʻoikaika i ka iodine meaʻai.Hiki ke hoʻohana ʻia no ka paʻakai paʻakai, ʻo ka dosage he 30-70mg/kg;ʻO ke ʻano o ka meaʻai keiki he 0.3-0.6mg/kg.
(4.) ʻO ka pāpaʻa iodide kahi meaʻai iodine paʻa.Ua ʻōlelo koʻu ʻāina e hiki ke hoʻohana ʻia i nā meaʻai no nā pēpē a me nā keiki liʻiliʻi, a ʻo ka dosage he 0.3-0.6mg/kg.Hiki ke hoʻohana ʻia no ka paʻakai papaʻaina me ka nui o 30-70mL/kg.Ma ke ʻano he ʻāpana o thyroxine, komo ka iodine i ka metabolism o nā mea āpau i loko o nā holoholona a me nā moa a mālama i ke koena wela i ke kino.He hormone koʻikoʻi ka Chemicalbook no ka ulu ʻana a me ka hana hou ʻana o nā holoholona a me nā moa.Hiki iā ia ke hoʻomaikaʻi i ka ulu ʻana o nā holoholona a me nā moa a hoʻoikaika i ke olakino kino.Inā nele ke kino holoholona i ka iodine, e alakaʻi ia i nā maʻi metabolic, nā maʻi kino, ka hoʻonui ʻana i ka goiter, e pili ana i ka hana aʻalolo, ka maikaʻi o ka waihoʻoluʻu ʻaʻahu, a me ka ʻai ʻana a me ka absorption o ka meaʻai, e alakaʻi i ka lohi o ka ulu a me ka ulu ʻana.
