ʻO ka waikawa DSD (4,4 diaminostilbene mono-2,2 bisulfonic acid) kahi mea hoʻoluʻu koʻikoʻi, i hoʻohana nui ʻia no ka hana ʻana i nā mea hoʻomālamalama fluorescent, ka melemele G paʻa pololei, ka melemele R pololei, ka ʻalani F3G pale lā a me nā mea ʻai anti-moth. ʻO ke COD he 6000-8000mg/L, ʻo ka paʻakai he 6%-8%, a ʻo ke kala he 50,000 manawa; ʻo nā ʻāpana nui o ka wai hoʻoneoneo he mau hui organik ʻala me nā hui nitro, amino a me sulfonic, a ʻo ka lakio o BOD i COD he 0.03 wale nō, he paʻakikī loa ia e biodegrade.

Paʻa ka maikaʻi o ka wai a me ka nui o ka wai o ka wai hoʻoheheʻe waikawa DSD, akā kiʻekiʻe loa ka chromaticity a me ka nui o ka sulfate, nele nā ​​​​meaʻai e like me N a me P, a loaʻa i ka wai hoʻoheheʻe nā mea ʻawahia a me nā mea ʻino, ʻaʻohe laʻana lapaʻau holomua ma Kina. He ʻano ʻūlū melemele māmā a pauka paha ka waikawa dsd, hiki ke hoʻoheheʻe ʻia i ka ethanol a me ka ether, hiki ʻole ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka hopena alkali. (2) Hiki ke hoʻoheheʻe maʻalahi ʻia i ʻulaʻula, a loaʻa iā ia nā waiwai o nā waikawa ʻala a me nā amines i ka manawa like.

3) Ka maikaʻi o ka huahana a me ka helu loea: ka huina waiwai amino (e like me ka nui o ka hoʻopili) ≥48%; ka huina waiwai amino o ka huahana maloʻo (e like me ka nui o nā laʻana maloʻo) ≥95.0%; ka nui o ka mea alkali insoluble (e ka nui o ka hoʻopili) ≤0.05%; ka nui o ka mea alkali insoluble (e ka nui o ka pauka) ≤0.08%; ka nui o ka benzyl (e ka nui o nā laʻana) ≤0.25% no ka hana ʻana i ka mea hoʻokeʻokeʻo fluorescent, .... Melemele hau G pololei a me ka melemele pololei R, a hoʻohana ʻia ma ke ʻano he insecticide.

ʻO ka pōkole hui organik. ʻO ka inoa piha ʻo 4,4`-diaminostilbene-disulfonic acid. Hiki ke hoʻohana ʻia no ka hana ʻana o ka mea hoʻokeʻokeʻo fluorescent a me nā kala ʻē aʻe. CAS No.： 81-11-8 Formula Molecular：C14H14N2O6S2 Kaumaha Molecular：370.4008 Index Quality（Specification） ʻAno（ʻAno）： pauka melemele māmā/paila melemele māmā ʻIke（Maʻemaʻe）： ≥95. 0 Hoʻopili（Pūʻolo）： 25 mg/kg.
