합성 Zeolite A 의 Detergent Builder 로써의 이용
김면섭,국명호 韓陽大學校 環境科學硏究所 1986 環境科學論文集 Vol.7 No.-
세제 builder로써의 합성 zeolite A를 하동 고령토로부터 합성하였다. 경도, 염화나트륨의 농도, linear alkyl benzene sulfonate와 합성 zeolite A와 sodium triphosphate의 비율을 달리 하는 세제 용액 중에서 non-finished cotton, resin finished cotton, polyester-cotton blend cloths를 세탁하여 세탁율과 칼슘이온농도를 측정하였다. zeolite A와 sodium triphosphate의 중량비가 1인의 경우의 실험결과는 다음과 같다. 세제의 양이 많을수록 세탁율은 증가하였으나 16˚d에서 3g/1 이상의 세제농도에서는 세탁율은 거의 증가하지 않았다. 세제농도는 경도 8˚d에서는 1.5g/1, 16˚d에서는 3g/1임을 알았으며 세탁율과 제거된 칼슘농도는 염화나트륨의 농도에는 무관하였음을 알았다. Synthetic zeolite A as a laundry derergent builder was prepared from domestic Hadong Kaolin. Non-Finished cotton, resin finished cotton and polyester-cotton blend cloths were washed in the detergent solutions which were containing various hardness, sodium chloride concentration and ratio of linear alkyl benzene sulfonate to zeolite A or to sodium triphosphate, and then cleaning performances and calcium ion concentrations were measured. The followings were the results of experiment in which the weight ratio of zeolite A to sodium triphosphate was 1. The more amount of detergent the more cleaning performance increased, but the performance was almost not inclreased with the concentration of detergent over 3g/1 at 16˚d. It was observed that the concentration of detergent was needed 1.5g/1 at hardness 8˚d and 3g/1 at hardness 16˚d. It was obtained that the cleaning performance and the calcium binding capacity were independent on the concentration of sodium chloride.
