EDTMPA ʻO ka pauka keʻokeʻo keʻokeʻo ma ka lumi wela, me ka helu hoʻoheheʻe 215-217 ℃, paʻakikī ke hoʻoheheʻe ʻia i ka wai, ʻoi aku ka liʻiliʻi o ka solubility ma mua o 5% ma ka lumi wela, maʻalahi ka hoʻoheheʻe ʻia i ka amonia. EDTMPA Loaʻa iā ia ka mana chelating ion metala, ʻoi aku ka nui o ka chelating mau me ka ion cuprum ma mua o ka EDTA.

ʻO EDTMPA kahi mea hoʻomaʻemaʻe kiʻekiʻe ʻaʻole ʻona, me ka ikaika chelating ikaika no nā ion metala, hiki ke hoʻohana ʻia i loko o ka ʻoihana uila e like me ka mea hoʻomaʻemaʻe no nā ʻāpana semiconductor o nā kaapuni i hoʻohui ʻia, a ma ke ʻano he mea lawe i nā mea radioactive i ka ʻoihana lāʻau no ka ʻike. a me ka lapaau ana i na mai.

Hōʻike:

Nā mea	Papa kuhikuhi
Ka nana aku	ʻO ka pauka aniani keʻokeʻo
ʻakika ʻeleu, %	96.0 min
Huina phosphonic acid (e like me PO₄^3-), %	82.0 min
Klorida(Cl^-), %	0.1 ka nui
wai, %	2.0 ka nui
Fe, mg/L	5 max
pH(1% wai hoʻonā)	2.0 ka nui

Hiki i kā mākou hui ke hana i ka 99% (chromatograph purity) a me ka huahana maʻemaʻe kiʻekiʻe ma ke koi o nā mea kūʻai aku.

Packaging a me ka waiho ʻana:

Hoʻopili ʻia ʻo EDTMPA i loko o nā pahu plastik, 25kg no ka pahu a i ʻole e like me ka mea i hoʻoholo ʻia e nā mea hoʻohana. E kūʻai ma kahi anuanu i loko o ka hale, ʻo ka manawa mālama he ʻumi mahina.

Palekana a me ka palekana:

He alkaline nawaliwali ka EDTMPA. E noʻonoʻo i ka pale hana i ka wā o ka hana. Hōʻalo i ka pili ʻana me nā maka a me ka ʻili. I ka manawa e pili ana, holoi koke me ka wai nui.
